Irish-

It depends on what I am having done and the cost of it in general. If I get my hair washed and cut I usually tip $6.00 ( I only maintain the length so they dont do much. The cut itself is only like $15-$20.

Getting a full set of fake nails on is usually $30- so I tip 7.00 ( bk when I did it) To maintain them its about 20- so i tip 5.00 / 6.00

I always tip a min on 20% on resturants- unless the waitress/waiter was horrible- even then I still do 15%

Hope this helps.
