free condom?

While I was out at dinner, I reached for my cloth napkin and was surprised to find a gift underneath it. I held it for at least ten seconds trying to figure it out because I initially thought it was a hand wipe. I was wrong. It was a condom. I hope it was just a joke because I would hate to think that the person folding my napkin or setting up my table was getting busy right before s/he touched my napkin.
