Sorry I just needed to rant. I am a waiter and I am sick and tired of people coming into the restaurant and asking for a million things, racking up a $40 bill, then leaving $0 for a tip. Heck, even $3 sucks for that bill. 20% is the rule people. Maybe it was 15% back in the day but times have changed. Unless they just have a terrible attitude the whole time leave a tip, you have no idea how stressful it can be to wait on 6 tables at one time. Also, the kitchen is to blame for most food mistakes. The amount of people leaving 0-5% tips makes me sick. I am trying to work to make money for college and people can't even leave a few bucks. Odds are $5 won't make a difference in their standard of living, but it makes a huge difference in my life.
