Tipping

This hand infographic is from Jezebel.com

yrmama dutifully admired her new haircut with a hand mirror with a slow spin in the twirly chair then followed her haircut lady up to the register. She declined to pre-schedule the next appointment and pulled her Mastercard out of her handy phone case while the haircut lady rang her up.

"Do you want a receipt?"

"No thanks."

OMG she's going to hand me the slip and I forgot to pre-figure the tip. 20%? Move the decimal one place = 10%, then double it...okay it's $47.50. Shit it's an odd number and a fraction as well. Now what? There's a seven. Seven times two is fourteen, round it up to be generous, fifteen. Add $15. Now for the adding. Meanwhile the haircut lady is politely waiting. Shit, carry the one, scribble out the five that looks like a two and make it a five. Okay, it's added but she's waiting for me! No time to double check! It's a fucking timed test and everyone else is done! Pencils down!

So once again I've overtipped. A while back I had a similar incident and ended up giving her about 40%. Out of mortification I then simply didn't tip at all for a few haircuts. So now she thinks I'm really weird and give huge tips but only occasionally. Perhaps the graceful way out is to find a new haircut lady, but then she'll think I don't like her work, which isn't true.

WWYD?
