Four to six bucks. If you get some special design or something, maybe ten. The better you tip, the more likely they are to remember you. And if they know you personally, they will do their best work when you come in.When you get a full set of hand nails, what is an appropriate tip?
i usually tip 5, but i agree with Shan. If you tip nicely then they are more likely to rember you. by tip nicely i mean smile, say thanks, and then give the money.
