My stepson has a similar problem he goes into the store alone and most of the employees know him and come up to him to shake his head, congratulate him, etc.
He goes into the same store with one of his friends and loss prevention follows them around the store.... Police are usually in the parking lot when they go to leave....
His friend is a known hoodlum, he has never been caught stealing, but just general bad news.....
He also happens to be white....
Is the store racist, or has the friend just made a name for himself....??
