I was watching Curb Your Enthusiasm this morning and there was much discussion about tips. What kind of tip rules do you all follow when it comes to certain services (not just food)? -Restaurant -Bar -Food delivery -Haircut -Moving services -Repair technicians -Valet parking -etc. For myself, I usually tip 20-25% with a minimum of $5 for most services. The cable and internet technicians had to come to my house plenty of times in the past and there is always an awkward moment where it becomes obvious that they are expecting a tip. I refuse to tip them because the service is never actually fixed I am being inconvenienced by their service being down in the first place. I'm a little lost of the etiquette regarding movers. I always offer them water and help them out as much as possible, but what's the rule on tips?
