I contacted my senators and representatives about how the IRS should classify tips made before service. I got a call back from my senator’s office. The reasoning I presented was: that automatic gratuity for large parties is taxed differently than actual gratuity in some jurisdictions (why those have disappeared in most places), and that since the tip is used to determine order priority it is not a tip but is instead a bid for preferential service.
I also went through a call to get back a tip I made on a Chipotle order (DoorDash I believe) up front after the driver failed to find the address and then chewed me out after driving through parking lots for 5 minutes.
