We go by a rule of whoever starts the car gets the tip, unless the customer says who it’s for or if it’s to split

Fuel attendant here. I don’t expect people to tip at all unless they’re asking me for favors. You’re cool if you’ve never tipped just for getting gas but you’re a pretty shit person if you’ve had fuel attendants check your oil or put air in your tires for no tip. I’d say like 2% of NJ plates tip, whereas like 40% of out-of-state plates tip, and are sometimes astonished that it’s not standard to tip
