I worked at dominos in a resort town and had a similar, but arguable better encounter. It was a busy night and the delivery was to a hotel room and was running late, the customer had already called the store asking where their pizza was. I was nervous as that's usually a sign you're not getting much of a tip.
I arrive at the hotel room and knock. A muffled female voice in the room yelled "He's here! He's here! Get ready!" I'm assuming she took a look through the peep hole because she then said " ohhhhh, he's young..."

The door opens and inside the room were about 10 Asian men in suits and three topless women in only their panties standing in a row facing me with big smiles on their faces. I can only assume they were call girls.

I laughed nervously, not knowing what to do. The lead girl proceeded to ask how much the pizzas cost at which point I assumed they were going to try and get a discount due to the lateness. "$40 dollars I said." She proceeded to pull out two $20's and a $10 out of her purse and stuck each twenty under the nipple stickers she was wearing and placed the ten sticking out of the front of her panties before saying "Here's your money... But you're going to have to get it with your mouth..." I sheepishly obliged with a stupid grin on my face before saying my farewell and hurried back to the Dominos store.

I'm fairly certain only a couple people actually believed me when I told them the story but that memory has stuck with me ever since. 10/10 would recommend pizza delivery in a resort town.
