I completely agree, tipping has gotten WAY out of control. I don't tip the Starbucks Barista's any longer, do you tip your Taco Bell server? It seems ridiculous to me. Pet salons, now expect tips. Years ago, this was not someone you tipped.
When I get my nails done, I usually only tip a few dollars, never more than 5. The salons near my home are always jam packed, where waiting can be 30 minutes on a normal day. Then I sit for an hour or more for the fill and pedicure, where the tech doesn't say two words to me, but talks in Vietnamese to her co-workers or on her phone. I find this to be extremely rude. One salon in the area, ran by Vietnamese family, has signs up that if the Tech answers her phone while providing a service, then the service is free. There is also limited conversation in their native language. I tend to tip along the lines of the 20% at this particular salon. This is the service I expect.
I think far too many people EXPECT tips, instead of having a mind set that it should be EARNED. There's my two cents.
