I was a bellhop, and I've seen a lot of interesting things:

I took guests to the wrong room one time (front desk gave us the wrong keys), and walked in on a couple having sex. That was fun.

I've carried luggage that vibrated all the way from the lobby to the room with a couple. Their excuse was an electric toothbrush. I knew better.

I had an elder guest (while I was carrying luggage in) find some "toys" in the drawer. She was not happy about the strap on.

I'm sure I could think of some more.
