Heh. I got lucky... must have been in the same room as you.
I was hanging around after the course in the room, trying to call into the office and talk to my boss. Saw a couple of people up at the table... not being obnoxious at all, but giving the people a little bit of a hard time over not getting the bag.
I gave a sort of sympathetic smile to one of the ladies with a "what can you do" look.
A minute later she came over and asked if I was attending any of the afternoon sessions. I said "no". She then asked me to give her my jacket, and meet her in the hall in 2-3 minutes. I gave her my coat, and sure enough, 3 minutes later she met me outside, handed me my coat with a smile, and said "have a nice day". The bad was tucked inside the coat.
