Fun topic! I've enjoyed play much like what you are describing, in one form or another. One experience, that comes to mind was with a client/friend who was into humiliation and age play. I buckled him in the backseat of my car and drove him to a restaurant along the lines of Olive Garden. I had a diaper bag full of toys, a bib and a sippy cup. I privately told the server, who happened to be an attractive young lady, that my friend was a little simple. Our lunch was pretty much what you'd expect with a mother and her three year old, right down to cutting up his food. The server brought him a balloon. We had fun and didn't seem to bother anyone. But, on the way out, the waitress gave me a half smile as if to say, "Yeah, right, you goofballs."
