Bad Luck and Trouble...

Sometimes I have to let the rat bastard GM in me out to play...

Bad Luck: The characters have some bad luck in one of their endeavors that sends their operation pear shaped: their observation post is compromised, a law enforcement officer recognizes one of the more-unsavory PCs, a barking dog blows the whistle on a night reconnoiter, a piece of important equipment catastrophically fails. The GM should consider how best to screw the characters with a bit of bad luck in a common and believable manner.
