You may or may not know that I have quite the collection of etiquette books. Never hurts to know which fork to use, how to compose a note of condolence or regret, and the like. But here's an unfortunately NOT hypothetical situation I experienced today that had me at a complete loss: When your hairstylist is cutting your hair and, in the process, inadvertently cuts off the tip of her own finger, is it OK to walk away in the middle of the haircut? And, if you stay in the chair because she insists she's fine (even though she tells the other stylists she'll be going to the hospital shortly, and you can see the blood from underneath the three band-aids she used), and she finishes your haircut, and you don't like it, is it OK to say something? And what percentage tip should you leave to compensate for the, uh, tip *she* left?
(Yes, I stayed in the chair; no, I didn't say anything; yes, I left a $6 tip for a $14 cut. Glad I told her up-front I didn't want a blow-dry)
