Look, I know that the tips here are ridiculous. But this topic is about how to tip in the USA. If you don't like it then get the hell out of the thread -- I'm speaking the truth. What I say is a fact and if you don't like it, then you can just leave the thread and shut your ignorant face. When I travel to new places I research what the custom is and do it. I don't write anonymous paragraphs on how that culture should do it. Grow up.
"Oh, vegetarians don't eat beef? Let me shove this steak in their face and tell them how delicious it is."
Sorry, that's the culture. See above.
"Oh, Afghanistan doesn't allow liquor?! Well I'll just bring in some Jack Daniels."
Yeah, great logic you've got there Moogle.
