I might tip if the guy decided to wipe my windows, but other than that never. Not because I don’t think they don’t deserve it, because I’ve lived in Jersey my entire life and it’s never been a thing here. You go, fill it regular, (or 20 regular) they fill it, wait for attendant to come back and take the pump out, then have a nice day. I’m going to be lost if I ever have to move out of state 😂
