I'm in a somewhat strange position of running a conference where there is going to be a cocktail hour that I had to arrange for the catering, including getting the bar service included. I didn't think twice about filling out the form to get the approval for alcohol to be served, but I have thought about what to do during the hour when people will be having their drinks. Now, this isn't likely to be a big drinking bash, but I am planning on excusing myself after one soda to attend to making sure things are set up for the speakers who will be giving their presentations following people having had their dinner. I may end up putting coupons for one free drink into the arrival bags for our participants, but I will be abstaining for sure.
