The empty table
Waitlist

Problem
Someone cancels. The table sits empty while three people would have come in an hour.
What you sell
Owner taps slot free. Bot texts the next three: you have 15 minutes to take it.
Week one
Collect 10 people who already said tell me if something opens. Run one real cancellation as a test.
Money
Setup 100–250. Then 20–40 per month. Add-on, not week one unless they are full.
First message
When someone cancels, the table dies. You tap once, the next three get a message. 150 setup, 25 a month.
Trap
Speed is the product. A pretty app they open in 10 taps is a fail. Empty rooms do not need this.
