They are checking IDs of everyone entering the area where they are selling bottled beverages (which include beer and wine). I thought the guy was joking, then realized it must be b/c of the alcohol, told him I was just getting water (and really, dude, it's been a few decades since I was under 21) and he said everyone has to show ID. I handed him my driver's license and told him it had been almost 15 years since I was last carded, he laughed and said "You're welcome."
Oh, and the bag checks are getting stranger and stranger. When I got here for the men, the guys at the door waved me through a non-bag lane and didn't look at my bag (so I guess i didn't need to stuff my packaged sandwich in my jacket pocket), no metal detector either. Tonight, when we arrived for the pairs, we were sent to the bag lane, but no x-ray or searching, we just had to put our bags in a holder of sorts to walk through a metal detector but never looked at the bags. Whatever...
