I used to work for the mall in the maintenance dept and I remember the guy you are talking about. Very creepy.

I used to work at the cosmetics counter when it was Higbee's about 1990. We used to refer to this area as the "Primordial Ooze" from whence the lowest forms of life would slither and come to annoy us while we were trying to get our work done. The SAME people came to the mall EVERY DAY and would hang out here. One of our favorites was well-known to the police and christened "The Perv." He would stroll in daily with his cup of coffee wearing sunglasses and loose-fitting jogging shorts. Then he would sit in this recessed area outside the store with his legs spread... You get the picture.
