Nothing new here. I used to work as a security guard at veterans club that had a live music venue. We often had undercover cops come through to check up on us or be part of the crowd to pick out trouble makers. The stupidest incident was being told not to give any grief to the dude in the Superman T-Shirt as he was a undercover copper - and yes when I spoke to him after the last patrons left we was a complete tosser.
heheComplete.No parts missing then :)
