In my cong there were a lot of depression sufferers and a couple with M.E. I was told that one of the back rooms was named the B.O. room as thats where all the brothers and sisters who were allergic to everything had to sit.
There was also a lot of common colds floating around most of the time as quite a few people would still attend the meetings even when contagious :(
I bet it was worse than a doctor's waiting room.
