I have a regular I see in Vegas. She introduced me to her "friend" with the warning that the girl was known to steal. While we were resting, the second girl gave me a tutorial on how not to get stolen from. She showed me how she could hook her foot on the desk chair, drag it over, clean out my wallet in the pants hanging on the chair, push the chair back, while never leaving the bed while I was in the bathroom with the door open. She had many other tips, but my advice is stick to ones you know.
