I work at a certain Dollar store. I probably see more than a hundred customers a week. Sad to say, that when other co-workers of mine have put police reports with pictures of customers that have committed crimes on SM, I have a hard time recognizing them. The problem with me is that I associate them being in my store not in a mug shot and or grainy picture such as the one of BG. The funny thing is that I'm really good at recognizing people I've worked with in the past or knew at certain times in my life. So here's my point, unless I've had some kind of interaction with someone (a conversation with them while I'm checking them out and see them again and brought that subject up another time) I'm probably not going to recognize a random customer who just came in once. Unless of course, something caused the red flags to come up. Oh, let's say something caused them to be angry and I noticed I had never seen them before. But even then, after a while that kind of fades in the memory. Just throwing this out there... IMO JMO
