Short version: I was at one of my "haunts" last night and we got hijacked. Which is to say, two men forced their way into the room and pulled pistols and made off with all the available cash. No shots were fired and no one was seriously hurt --the door-minder got two scraped knees from wrestling at the entrance with the intruders. This is why I rarely carry cash to the games; if I lose, I go to the ATM at the end of the evening (never alone) and settle accounts post-haste. I lost no money personally.
Disturbing aspect: poker room robberies are never random acts. Someone knew that there was a game in that location, at that time. (As the holidays approach, some games shut down for lack of players.) As the game had only started very late and had tentatively broken up early in the evening, it had to be someone who had called in during the evening to see if a game was going on. Which means: someone everyone knows acted as a "scout" for these two gangsta clowns. I have my suspicions.
