One of my previous supervisors was NSFW. Saw her doing coke in the office of a bar I worked at (though I saw me do it too... teehee), she also let us steal like 5 or 6 cases spirits which were old stock (drinking the vodka/gin/rum from the back of the shelf an filling it up with water). Both acts are frowned upon to say the least (though I benefited so didn't care) but what takes the cake was when she attempted to pressure me into commit sexual harassment/gross misconduct.
A fairly hot girl came to the bar asking for help, she had dropped her card on the floor of the ladies toilets and it had fallen between the floorboards. Ignoring the fact she had her credit card out in the toilet (who am I to talk) I went to help her an try to rescue it. She points to where it fell, I go look and she then locks us both in there! (Yay!) She grabs me, we make out a bit, then she takes off her top and reaches into my trousers and says 'fuck me'.... I'd originally volunteered to help as I thought if I helped her she might give me a cheeky line! I was more than willing to take a drunk chicks coke. I had not been expecting sex, and while making out was fun and harmless, I wasn't morally void enough to fuck a drunk chick...
So I said no, needed to get back to work, maybe go for a drink some time? She then asked if it's because I thought she wasn't pretty... Looks like I made the right call! "No, obviously I think you're hot, I want your number blah blah blah.." I go back to work and 10 minutes later she comes out of the toilet crying. I definitely made the right call. Well done brain.
So, 'In the office' with my supervisor afterwards, and I told her what happened. She tells me an idiot for not fucking her and then checked the CCTV to see if the drunk girl was still there! She says she'll go downstairs an invite the drunk girl to the office and that we should have sex in there! I then made a mistake and jokingly said "Well, I don't think I can turn down sex twice. If she comes up here..." and my supervisor took this seriously, an seemed intent on bringing her up, when were done in the office... I seriously asked her not to and reiterated my moral conflict but she was still carrying on like she's do it. Only a threatening to call our boss got her to stop! (ayyy blackmail always does the trick). So, my supervisor's lack of a moral compass is and eagerness for me to take advantage of a drunk chick is definitely the most NSFW thing I've seen. That may even make my supervisor not safe for work.
TL;DR: I'm a saint (by very liberal definition), my old supervisor is not. She's NSFW.
