I'm sure that tipping varies a bit, depending where you are. Here it is customary to tip the garbage men, postal guy, delivery guys etc, during the holidays. Is it so where you are? We had our carpets cleaned recently; the whole house. Two guys came and moved the furniture and got it done in about an hour and a half. They did a good job. I tipped $20. I did the same last year. I know you aren't supposed to tip a salon owner when they do your hair, but I see people doing it all the time, here. It's customary to tip a hair stylist 20% here. Do you tip your dog groomer? I used to if it wasn't the owner, now it costs me $45.00 just to groom my dog. Since they are the owners, I don't tip anymore. How much do you tip the groomer? I'm also curious....who else do you tip? How much?
