Yep, I’ve done it. One time a bunch of us went out to dinner in San Francisco with a friend’s father treating us. After dinner, we went to the Hyatt Regency for an after dinner drink in the rotating bar. As we were leaving in the elevator, the elevator stopped outside a ballroom where a reception was going on. My friend’s dad said, “come on!” and we all went in. We had some drinks and did some dancing, including dancing with some of the guests! Then we left after about half an hour. It was a lot of fun.
