i used to work in closed-door office space (big building with a bunch of smaller rooms with multiple work stations) with all guys. there was no air-flow or ventillation in that room and let me tell you, there were smells. one of the guys was particularly sweaty and one of them was particularly gassy. let me tell you, regardless of the close quarters and the fact that we could all clearly see eachother with desks back to back, i used lots of spray and candles.
