Can I get a tip?

As the ongoing joke from Wedding Crashers would make this title a joke, the frustration I have for people who don't tip the workers of the restaurant industry makes it a serious topic. I've worked in several restaurants of different dining experiences and they all seem to bring the verbal tippers, or the I feel like I deserve my food right now, or the people who just have an overall negative attitude towards their servers. Some people maybe truly don't understand how hard the servers, bussers, bartenders, really work, but if your making that claim then try going to a restaurant on a busy Saturday night and just open your eyes. I think I speak for all restaurant workers when I say, Tip your servers, or go home.
