what is it about motels attracting the idiots in the area and drawing them in?

We have had this idiot who is obviously off his rocker come in several times and making a commotion each time hes there. it has gotten to the point that he was posing a threat to my manager and she ended up calling the cops and now the idiot has a trespassing charge on him. -sigh- idiots idiots idiots ... what is with them all.
