The last time I got my hair cut, I didn't tip anything. I was so upset by their prices, I figured they had gouged me enough. I had burned the very edge of my hair (long story short, don't be lazy and dry your hair by using your gas space heaters, just pull out your hair dryer) and went to have it trimmed off so I didn't smell burnt hair every time I showered. I thought they would cut a couple of inches off since I told the lady to cut off the damaged area. She cut about 1/4 of an inch, took 5 mins and was done. You could barely see my hair on the white floor (I have red hair, so it shows up). She then charged me (after tax) $16. I didn't tip, I barely had anything done and I figure $16 for 5 mins worth of work (7 if you count ringing me up and putting the apron on me) was pretty good. I also don't plan on getting my hair cut until it gets to my elbows (It's now mid back) or until DH gets sick and tired of laying on it every night.
