Went to the hairdresser, wanked him seven quid on top of the hair biz (came to £55). Didn't wank the hairwasher woman, who was okay, but not great. I would have wanked her, but didn't know how to do it...do you give them money? Do you shove the money into their hand, like an enthusiastic uncle? WHAT DO YOU DO?
Do you wank? Do you decide on percentages? Do you have concerns about the practice?
