Friday i told the teller at the bank when asked if there was anything else she could do i told her to tell her coworker(who was on the phone behind her) that she was a jerk because her shirt(blouse?) made me want lemonade (white shirt with a repeating lemon print, wasnt sure what it was and took me a bit of looking at it to figure out what it was, but had the time while the teller was processing my deposit)

Of course both of the bank people know my first name as ive been there before and i used the person's name.

I maybe would have said something like that without having met them before, but it would really depend on the scenario and environment. Likely i would have said nothing if there wasnt enough time to explain if it wasnt received well, which isnt always the case in public.
