For college instructors, what's your opinion on students using profanity in conversation with you? I had my first week with a new lab today, and one girl already managed to drop several shits and fucks, one example being (roughly quoted) "Oh yeah I'm on the roster, right there, I'm a fuckin Mexican and we all have long as hell names". It's a loud general chem lab and I would expect a bit of similar banter between peers, but it's just kinda weird having it shamelessly spoken like that to me. Where do you guys usually draw the student-instructor professional conduct barrier?
EDIT: Slightly related, in the brief periods when they weren't wearing their labcoats (entering and leaving), I saw much more cleavage than ever before when teaching. It was almost ridiculous, actually. I think I have pretty good eye control though.
