So not really an AIBU but more of a WWYD.
I have a colleague / work friend. We started as colleagues with me in a supervisor role but have developed a friendship in that we get on very well, chat about life, dont see each other really out of work but will often spend time together at work events cos we like each other's company.
In certain work social situations she has a tendency to drink a bit too much. That's fine, I'm not the police, but occasionally it becomes a little cringe from a work point of view as it isn't reduced around important business contacts. She is an ok drunk in that she is friendly and happy but can get loud and sweary. Amongst friends that's fine but not really appropriate when networking.
I don't want her to do anything daft but also don't want to be on her back. Not sure if I take the supervisor role and tell her it's not ok but also don't want to be a dick. She's a nice girl and don't want to hurt her feelings. Help?!
