I imagine they're not SO stupid that they'd be bunched up around the door.  They would however be lined up about five feet apart or so, with at least one of the support pillars on the farthest left of the room right next to the last on that side, so he'd have some cover, but only from the direction of the bar if that makes sense.  There's a few pillars evenly spaced around the first floor, but they're near the corners and holding up the second floor balconies and the stairs and stuff for the most part.  Hope that helps overall though.  :D
