I'll give them a tip, find a better job

I don't tip if I haven't gotten my food yet.

>Literally a button to select 0%
>Doesn't push it

Is it just so that the cashier sees you pressing more than one button

>pretend you gave a good tip and smile at the cashier
Are you fucking illiterate?

You can press 25% and it would look the same as pressing "no tip"

Did you stop reading mid post?

one time this happened and i put every cent left in my account as the tip (paypal) and they got offended because it equaled like 5% and i told them to go fuck themselves

I fail to see how this is any different than any other method for tipping
