At Flag they were extremely strict on it with SO and OOTs but not very strict on it with the newbies cos sometimes I'd be almost gagging on the smell of some of the div 6 public's perfumes. Can't go offending and scaring off the future sheep for the flock.
However I remember being on course at AOSH ANZO, as a public, and twinning with this guy who had used a LOT of b o spray and although it was actually a totally natural tea tree based product the smell managed to fill the course room in about five minutes. No sooner had we started drilling TRs when the sup goes "what is that smell," really loudly, and I could see her from the corner off my eye sniffing at the air like a good ol' hound dawg and following the scent. My TRs must have been good cos somehow I managed not to

at the sight of that. She finally followed the scent to us and then ordered this poor guy to go to the toilets and wash thouroughly before coming back to the course room.
