Search Results: transferring schools

My high school daughter eats out for lunch almost everyday, and thus she is able to remember a lot of faces who are not students but goes to the same places she goes to. A few months ago we moved and she thus transferred to a new school, which is also beside a mall. Of course, she eats there frequently for lunch too. Remembering the faces at this other mall, she has noticed one face that has appeared in both malls during school lunch hours, a middle-aged man who she sees about once every 3 weeks. She decided to take a picture of him eating, and sent the photo her friends from her former school, and indeed they do confirm that the same man is (still) eating lunch at the mall beside their school about once every 3 weeks. Digging further, they showed the photo of the man to their other friends from several other schools. So far her friends from 6 different schools have confirmed that they see the same man eating at fast food places next to their schools, frequenting about once every 3 weeks. All of them report him leaving line-ups that seem too long for his patience, then when he finally gets his meal, he eats it without interacting with anyone (and hardly looks at anyone because he usually reads a book while eating), though he does sit at tables beside students when the food courts are full. So all in all, they report that he is not harassing anyone, but they do find it odd that he goes to precisely the same food places that students go to across several different schools, and repeating each school once every 3 weeks too. What should be done about this? Should they inquire him about this? Should they report the man to security or to their principals?
