20%. Yes she owns the salon and she rents the spaces BUT due to my eratic work schedule, i often have to reschedule my appts. I try to give a few days heads up but still an inconvenience for both of us. I justify the tip in that I don't buy her a Christmas gift (suggested amount is the full price of the salon visit). I feel like I am generous every month. She does a nice job on my cut, color, highlights, etc. I have been going to her for 12 years...even prior to her buying the shop.
