When I was in high school, I encountered the first woman I had seen to have a moustache of more than barely-perceptible peach fuzz. Though it wasn't a full moustache like most men would have, it consisted of relatively long, dark hairs. She worked in the cafeteria as a cook/server.
I had completely forgotten about her until I heard a funny song Adam Sandler wrote about the school lunch-lady. He referred to her as having a moustache. I thought it was an unlikely coincidence that the lunch ladies at both our schools had moustaches.
Then on a hunch, I asked four other people at work if they remembered the cafeteria workers from their high schools. Of the four, three remembered at least one of them as having a moustache like I described above, and one simply couldn't remember anything about having lunch in school. Discounting the one who couldn't remember, we're five for five on mustached lunch-ladies, counting Adam Sandler and me.
What's your experience? Did your lunch-lady have a moustache? Granted, a poll of five is by no means statistically significant, but does anyone have any ideas as to why mustached female school cafeteria workers would be commonplace?
