well i work in a resturant and i see bad tipping all the time... and it sucks..

especially cuz sometimes its not the servers fault, the kitchen fucks up at times and so does other things, but the people take it out on the server....

i always leave at least 15%, and thats with really bad service...

and i dunno why but it seems native americans usually dont tip well, not tryin to be mean but its just the way it is, and they are not poor they buy the most expensive stuff on the menu...
