I've done this a LOT, so I'll just give the best one!
I did this at a hotel in Wisconsin. I left a note in my room explaining that I wear diapers, but they leak at night sometimes, and could they put a plastic sheet over the mattress just in case? When I got back, they had used some sort of plastic sheeting - VERY noisy. Anyway, I was pretty ....um... "excited", shall we say, and I called a Phone Mommy.
She decided I needed to be punished for making extra work for the housekeeper. she made me have a self-spanking while she listened, then I had to write an apology note since I liked writing notes so much! I had to give the note to her in person and get it signed to prove I did it. In the note, I had to apologize for the extra work, and ask that as punishment, I have to clean the room myself.
Now, I don't know what this housekeeper had seen in her life, but her face never even changed expression as she read my note! She just told me that was okay, and she would clean my room. When I stressed, "But it's my assignment!" she relented that under her supervision, I would strip my own bed, change the towels out, and clean the sink, mirror, and potty (how ironic). She had to do the rest though, or she could get in trouble. She also signed my note.
:: Giggle :: I've often fantasized about that, that she would have gone further, putting me in a corner for awhile, or bending me over the bed and giving me a spanking. I think she HAD to have been into BDSM or something at some point, since nothing shocked her in the least (the note even had my confession that I had been spanked for my misdeed), and she seemed to catch on immediately when I said it was my assignment.
