Not tipping in most foreign countries = acceptable.
Not tipping in the US = cheap, loser faggotry. And leads to spit, boogers and jizz in your food.
And that is todays international lesson, kids.
truth, if you plan on eating at a place again, you got to tip. That's just the way it is here.
Some of my friends used to be waiters, they say that everyone hated waiting on Mexicans(the ones from Mexico

)
They are rude, demanding, and don't tip.
