With the exception of wait staff, manicurists, and hair stylists, do you ever get in those awkward moments when you don't know if you're supposed to tip someone? For those living in NYC, should you or do you tip your doorman? Another question: Do you tip your esthetician when you get microdermabrasions?? I'm good friends with mine so that's not an issue but what is standard practice? For those in the profession where tips are highly depended upon, do you have any crazy stories where you've bent over backwards only to receive a lousy tip or vice versa?
