So what I'm reading is a truck driver can invite as many guests as they want to shower with them there, so long as none of those guests are also truck drivers.
Weird rules for the orgy shower, but who am I to judge?
I think it was joke. You are the one that decided to take it as political. Also, probably shouldn’t try to come as “better than thou” when your username looks like a 13 yo sat down and tried to think up the grossest thing they could while nonstop snickering to themselves the entire time because of how edgy and funny they are.
I started work at a place, and heard a story of a lady who caught two guys in the women's showers the day before. I don't think a sign on the door is going to change much, certainly not after that day.
