In grad school, it was a given that profs and students drank together. After all, no one can work that many hours for that little glory without a serious cocktail habit. (or maybe that was just me?)
If you teach at a PUI, the majority of your students are under 21. I certainly wouldn't go grab a beer after classes with any of them. THAT is frowned upon here.
But what about at conferences? Drinking is an integral part of research conferences. (or maybe that is just me?)
If an undergrad is 21, would you invite them out with a group of colleagues for drinks? What about former group members from grad school?
