Why am I such a fat nosy bltch?

Whenever I am cleaning at the motel I work at, I tend to go through the people's drawers and even eat their leftover foods or raid their mini bar. I know what I am doing is wrong and I dont intend to steal it just happens. It starts when I get the urge to go through their underwear drawer to sniff them, then I keep going and start stealing. If I get caught, I am sure to be fired by Mr. Peterson. How can I stop this?
