"In the UK we do not tip in restaurants"? Are you ******* joking? I am English, born and bred. Everyone DECENT tips in restaurants. Please, those of other nationalities, the statement above is not accurate of the UK at all (generally speaking, everyone tips unless they are unhappy with the food/service, it is never usually mandatory but it's just a polite social etiquette that most people adhere to).

I go in restaurants quite a bit, and never see people tipping, and generally, we don't leave the bill on the table with the receipt like I've seen it in most countries I've visited. Also, you can't really tip if you pay by card.

Well that's a bit silly :\ I don't know american customs :D

Waiter and waitress wages are very low in the US. So tipping is their major income from the job.

The only people who do not tip adequate money in restaurants are usually *******. Most ******* literally never tip, or just leave pennies and dimes, perhaps a quarter.

You are supposed to tip at least 15% of the bill. The waiters live off of said money, in many restaurants the tip goes into the cook's pay too.

You're an exclusion. Most nigs, as you should be well-aware, are not mannered.

There are literally entire forums dedicated to waiters and the biggest topic of criticism are black people.

is* black people.

I know many well mannered and unmannerly black people. The majority I know fall into the well mannered category. I just seems to me that people are more apt to remember encounters with ghetto, loud, and ill mannered black folk than the ones with black people that are more or less average. Do you know very many black people personally?

And that is why I feel more bad for this bitch. Venting on facebook and ending up unemployed in an age like this. That just sucks.

depends on where you are.
