is NOT spending an entire ten-hour-shift doing massage while the underwire from my bra is stabbing me in the armpits. Especially when both discreet and not-so-discreet adjustments fail to improve the situation. Oh, well. Back to sportsbra tomorrow.
Also not fun (this actually falls more in the category of pet peeve): Clients who've received a whopping discount (say, 50%), and then calculate their tip based on the discounted service price. Cheap!
