Except we were far from the end. And the ammo was in a room, you exit, and walk up stairs. We were at the top of a single stairway when a holy cluster of zombies dropped in. The crazy spawns that have you empty your assault rifle clip, reload, empty, reload, empty, reload. So all I did was walk back down the stairs, enter the room, refill, and walk back up. This dude was just in love with his own voice and had to constantly hear himself talk even if he was spouting non-sense.
As for people dawdling, this annoys me when people aren't paying attention. When you're badly injured, you walk slowly. Nothing worse than people running ahead and leaving slow moving wounded without cover. It's an endless cycle of rescues. Especially in versus when multipliers are earned for # of survivals.
