at restaurants I only tip because otherwise I could never go there again but when I can get away with it, I never tip

I always tip

Uber drivers deserve the tip, they don't make much anymore.

i never tip the person at my stadium who opens a beer. however when i was at a mnf game in new orleans once i ordered a vodka/soda. when i saw how much he free poured i gave him a pretty good tip. he remembered it and the second time was even better....yeah i was hammered by halftime ....who dat!
