A proposal for Warrior Stadium

Skip the line.
We'll bring it
to your seat.

Fans order concessions from their phone and a student runner delivers to their row. The stand sells more. Nobody misses a drive standing in line.

The problem

Halftime is 15 minutes.
So is the line.

Every home game, the same thing happens. The second quarter ends, everybody stands up at once, and the people who want a hot dog spend the entire break in a line instead of at the game.

79% Missed a play in line Fans who say they have missed a memorable moment while waiting to buy food.
80% Gave up entirely Fans who have walked away from a concession purchase because the line was too long.
10 min The patience limit The longest wait fans call acceptable. Past that, the sale is gone.
58% Would spend more Fans who say they would buy more if they did not have to wait in line.

The stand is not slow. One window can only serve so many people in fifteen minutes. Every fan past that limit is revenue we already earned and could not collect.

Mashgin fan survey, n=530, April 2025 · Oracle Food and Beverage survey, n=2,008, 2019 · Concessions rank among the lowest-scoring parts of the fan experience across 15,000+ fans surveyed (Deloitte, 2024) · Halftime length per NFHS football rules, 2025.

How it works

You never leave your seat.

A QR code is taped to the rail at every section. Fans scan it with their camera. No app to download, no account to make, works on any phone.

Not a concept

It is built, it is online,
and you can open it right now.

I did not mock this up for a class presentation. It is a working system with four separate screens, each on its own address, updating each other live.

This is a proven category

Schools already pay real money
for exactly this.

I did not invent in-seat concession delivery. FanFood sells it to high schools right now, and is the official digital concession provider for seven state athletic associations. The idea is proven. The only question is who builds ours.

What FanFood charges a school

Software platform$1,500 / year
Point-of-sale kit$959 each
Handheld / card reader$449 / $149
Every mobile order2.9% + $0.39

What Sideline charges the school

$0 for the software,
forever

No platform fee. No hardware to buy. It runs on the phones and tablets we already own, and on a server I already pay for.

+20% Concession revenue lift Owasso High School, about $6,000 over nine games.
+22% Bigger average order Independently reported for mobile vs walk-up ordering.
76% Fans who want this Say in-seat delivery would improve their experience.

FanFood published pricing, fetched August 2026 · Owasso HS via The Spoon, 2019 · Order-size lift: Appetize, 2020, and LSU, 2019 · Oracle survey, n=2,008. FanFood's own marketing claims a higher lift. I am using the independently reported figures.

Where every dollar goes

The app never touches
the school's food money.

A real receipt showing subtotal, delivery fee, tip and zero sales tax

Here is a real $9.00 order, exactly as the receipt shows it. Every line is separated before anyone pays.

$6.00 Food and drinkThe stand's own menu at the stand's own prices. To the school
$1.00 Delivery feeOnly on in-seat delivery. Express pickup is free. To the runners
$2.00 TipOptional, and the fan chooses it. To the runners
$0.00 Sales taxSchool concession food is exempt under Texas Tax Code 151.314. Exempt

The stand's share is calculated as the total minus fees, tips and tax, so the books cannot drift. Every order exports to a spreadsheet. For comparison, the CFPB found K-12 school payment processors charge families an average of $2.37 per transaction. Our delivery fee is $1.00, and it is optional.

06

Who actually runs it

Three students, one stand,
and a twenty minute training.

Runners are students I recruit and the school approves. Two or three per game is enough for our crowd size. They wear a marked vest, carry a lanyard, never leave the stadium bowl, and work fixed routes on the home and visitor sides.

The runner app is three buttons. Accept, picked up, delivered. It locks the delivered button for twenty seconds so nobody can fat-finger it and break the record. I train them in one afternoon.

The school pays the runners, not me

Delivery fees and tips land in the school's account with the food money. The school pays runners from it, either as hourly student workers or into a team's fundraising account. I never handle anyone's pay. That keeps it clean under labor rules and keeps the school in control of the cash.

A realistic night for one runner

Deliveries in a game18
Delivery fees earned$18.00
Tips at about 15%$21.00
Total for the night$39.00
Hours on shift3

Based on 60 orders a game, about 54 of them delivery rather than express pickup, split across three runners. Tips at the 15.8% quick-service rate Toast reports for 2026, on an average order near $7.50. If the volume is lower, the pay is lower. Nobody is promised a number.

What it costs you

Trying it costs the school nothing.

Who sets the menu and pricesYou doYou do
Who runs it on game nightYour staffMe and my runners
ContractAnnualOne game, then decide

If it works, here is what I would ask for

Not a cut of sales. A flat service fee, the same way you would pay any vendor, for running it on game night and keeping it working.

$125 per home game about $625 a season
or $350 for the season paid once, up front

Either one is less than a quarter of what FanFood charges before they sell you a single piece of hardware. My parents would sign the agreement with me.

Card processing is the standard rate any provider pays, currently 2.9% plus $0.30 with Stripe. It goes to the card network, not to me.

08

The honest part

What could go wrong,
and what I did about it.

Students walking through a crowd with food and money Runners never handle cash. Everything is paid on the phone before the order is made. They wear marked vests, stay inside the stadium bowl, work fixed routes, and check in with the concession lead.
Food safety rules Runners carry wrapped and lidded items only, in a covered carrier. Texas exempts volunteers from food handler certification, and temporary school stands from the manager requirement. Nothing about the food changes.
Who holds the money The school does. It goes into the school's own payment account, not mine. I do not have access to the funds and I am not the merchant on the receipt.
Cell service dies during the game Real risk at big venues, much smaller at ours. The page is 315 kilobytes and caches after the first load. If the network fails, the stand keeps selling the normal way and we lose nothing.
Older fans will not scan a QR code About a third of adults over 65 use QR codes, so I never assume it. The walk-up line stays exactly as it is, there is a plain list instead of the map, and the printed signs spell out the steps.
An order goes wrong or a runner no-shows The stand can void any order from its screen and the fan is refunded. If we run short on runners, every order switches to free express pickup and the system keeps working.

09

What I am asking for

Give me one game.

Not the season. One home game, home side only, with a cap on orders. If the numbers are not there, we stop and I have still learned more than any class could teach me.

The pilot

  • One home game, sections 101 to 106
  • Three runners the school approves
  • Express pickup on, delivery capped
  • The stand's real menu and prices

How we judge it

  • Concession revenue against a comparable game
  • Average delivery under six minutes
  • Zero missed or wrong orders
  • What the stand volunteers say afterward

What I need from you

  • Permission to run the pilot
  • One adult contact at the stand
  • Ten printed QR signs, I will make them
  • The go-ahead to recruit three runners
