Collect everyone's share upfront into one place held by whoever's running the grill, and buy the food, drinks, and supplies out of that table. No more one person floating the whole cookout and chasing everyone at kickoff.
Every tailgate crew has the one person who buys the meat, the drinks, the propane, and the folding tables, then spends the first quarter trying to remember who owed him what. Everyone says "I got you next time," and next time it's a different guy floating the whole thing.
Tailgates run on the honor system until the same person keeps eating and never chips in. A visible table fixes that quietly: everyone can see who's in and who isn't yet, and the app sends the reminder so the host doesn't have to be the one asking for money at a party.
For a whole season, one table can carry it: the crew chips in once, and every game's food and drink run comes out of the same record, so the host never floats a week and never keeps a tally in his head. (Turning it into a full party after the game? See collecting for a party you're hosting.)
The host holds the money the way one person always does, only now everyone sees every dollar. It goes through Stripe to the host; TableCash never holds it and is just the record.
