Went to the comic store on a late lunch today. As I got in the car, I saw the clerk locking the door. At 2:00, it seemed a bit early for closing, but then I noticed he had just hung up a sign that said:

AFK BRB

A bit cryptic to the uninitiated*, but probably completely understood by the target audience.

*And for the uninitiated, that’s “Away From Keyboard” and “Be Right Back,” common online abbreviations that have made the transition from IRC chat to modern IM. Though I suppose in this case it could be “Away From Kounter.” Oh, and IRL=”In Real Life.”
