How are my results? I am pleased to report that I have only lost my loonie twice. Once there was a younger, teen aged girl in the change room. I heard her take it as I was in my cubicle getting dressed, and she was still there when I walked back to my locker. She asked if I wanted it back when she saw me look for it in the slot. I said no, it's alright. I said I always bring extras, so it was no big deal (I do.) She just nodded and left. Why did I let her keep it? Because a) if you are stealing dollar coins at the pool, you have bigger problems and b) the guilt of letting her keep it would do more than busting her chops, in my opinion.
The second time I lost my coin was another time when teens were around. I have no idea who took it, but it was gone when I came back to get my shoes.
The coolest thing happened, though, on my very next visit to the pool. I walked up to my regular locker and although it stood starkers empty, a loonie was sitting in the slot! Ever so happy, as if I had just forgotten to pick it up the day before! I fed the karma train that day and left it there in the slot when I left. Hopefully that lucky loonie served someone well.
My conclusion: teenagers are silly and think they need to steal coins when they don't. Adults respect boundaries better.
