"Always overtip!" quote from Steve Martin in My Blue Heaven I can guarantee that you will never have to wait in line again!I recently found out it was customary to tip the stylist 10-15% I am an ex-server so I have always tipped 20%, I know that by overtipping has some priceless benefits, no cancellation fees, I never have to wait, just the opossite, I get bumped ahead of the non-tippers, the service is always personal and outstanding. I really love getting my hair done at the beauty school, I feel it's safer because the instructor is right there and the students really listen to what I want. Besides, the services are a bargain. Just because I'm saving money doesn't mean I skimp on the tip. They charged me $60 for a complicated cut and color so I tipped $20 the same percentage as if I had paid $100 anywhere else.
