Seems there's a website out there for those in the service industry to gripe about bad tippers! LOL!

Beware you chiap people! Not only will you get DNA in your food, you can get on a black list if you're not careful!

I used to be a waitress for years during college and good tips meant I had better meals, so come on you cinapeks. Fork it out for the good of all malnutritioned working students!

Hey, apparently, those in the service industry are pre-taxed for the tips they will get for the rest of the year. So if you give them a shitty tip, they would've been overtaxed. Is this true?

Of course, if the service is crappy, do what you must.

The general rule is double the tax, or 15-20% of the pretax bill. Check out this useful article on tipping in the US.

And this article for laughs.
