Back to topic here.
Based on many, many visits the chances of being caught are minimal (about the same as being trampled to death by an elephant on a Street). If you are, you will probably have to give your name and address but do not have to answer questions. As has been said here, choose carefully, and walk if you are not happy with anything. I dont mind being talked to the location on the phone by an escort and I bring a headset for this reason.
