Quoting kate♥[j&a]:" So my mom & I went out to eat at pizza hut today & the waitress there was awful. She didn't bring ... [snip!] ... tips to make up the difference. But do you think it's still necessary to tip a bad waitress/waiter who provides bad/no service?"
If you suck I won't leave you a tip. People bitch that "well thats their paycheck, they need to have a certain amount paid into the restaurant!" Well then do your job and you wont have to worry about losing money!
I have had horrible experiences, like one time a waiter getting pissed that they served me food with meat on it when I requested no meat, literally stomped off and just removed the meat and didnt actually give new food, and when I complained again he stomped off bitching under his breath. We had to talk to the manager and he gave us the stink eye the entire night. I have many experiences like that, and if you act like that... you might get my gum underneath my glass ;) Not really, but I won't tip.
