I went to a chain haircut place Sundee because I didn't feel like driving 16 miles roundtrip to the place that's actually really good, and calling first, and working around their schedule. The woman who cut my hair looked like a really poor man's (woman's) Megan Fox with some face tat and some borderline anorexia. Anyway, it was $26 ($20 about five years ago). I used my debit card. The minimum tip suggestion was $6. That's over 22 serpent. F off with that. Tipping is FIFTEEN PERCENT. It's not 21, or 18, or 27, or 42. My conspiracy theory is corporations push this nonsense so they can underpay workers. I will give 20 or 22 percent if the waitress or waiter is really really good, or the co-ed bartender gives me her number.
