When I worked as a barista, I was the only straight guy there.
The people I worked with would get hit on by major creepers all the time. It's usually a good idea to have them go in the back and have opposite gender deal with them (they would do the same thing for me when creepy ass women would come in).
We had one guy who we would refer to as Creeper Dan, and I had to call the cops on him for taking pictures of the girls through the window.
I always would have to deal with that fucker. And as much as I wanted to, I could never beat his face in for openly slobbering on himself if anything with a vagina was in the vicinity.
Stupid mandatory professional attitude.
