Same with my barber. Been going to him for about a decade & turns out he was even my neighbor for awhile. 1 man show & an enjoyable person. He did "frowned upon" cuts for regulars the other year so I doubled what I was tipping & have just maintained that since. I get my hair cut every 4 to 6 weeks, a tip isn't an inconvenience.The girl that does my hair is a one-woman show and she charges what she's worth. And then I tip her.
