Back in the 1970's our cleaning company was far larger, and our supply business relatively small. We did alot of fire restoration and large commercial jobs, so we needed a larger employee base than we have now.
I got quite an cultural education from the Vietnamese refugees among them a couple of high ranking officers who clearly had been both corrupt and brutal in South Vietnam, but of course very polite with us.
The most "interesting" group were three women who applied as employees together, and by grooming and behavior led us to quickly believe that they "didn't have any interest in the male employees" to put it mildly.
This had, of course, no bearing on their work status. They kept to themselves, worked hard, and we had no real problems until our youngest, most naive, and strictly religious employee (no, not me) walked in on the three of them at a work site. They were engaged in behavior that left the poor kid in no doubt as to the nature of their relationship, although even at that, the "threesome" must have made it even more of a stunning sight for the poor kid.
We had to let them go, of course. The other employees (more typical "shot and a beer" Pittsburgh types) were envious of the kid who walked in on them. After a few weeks of good natured teasing from our rougher types, he left us too.
I often wonder how he's doing, and if he's ever gotten over that.
