bad tipper
Someone acting like they put a few quarters in the tip jar when they really just dropped in 2 pennies also people who don't tip because it is "optional" and have no guilt afterward
Friend 1: yo, should I pay a tip?
Friend 2: nah, they're optional
Friend 1: screw it I'm not being a bad tipper
Friend 2: nah, they're optional
Friend 1: screw it I'm not being a bad tipper
