Family Dollar review: Banned while I was outside in car

A few days ago, maybe June 17th or 18th? I gave a girl a ride to Family Dollar near me #8172 on Hwy 60 in Superior, Az. I went with the intention of buying ice cream... I've been going to this store for years since it was first there, around 10-15 years, I am 67 and have worked in Customer Service since 1984. They had a mgr there who has retired - everytime I went in, Ann knew I was one customer they didn't have to be concerned with. However, on my most recent visit to the store, this new mgr (really has a bad attitude with people) saw the girl I guess take something ; but I was going to go in to purchase ice cream; That mgr had the nerve to step outside in the parking lot, point her finger at me (I was parked directly in front disabled) and tell me I Was Banned from the store because I brought that girl to the store. I was never so humiliated! She accused me of being "WITH" the girl; I have never ever stolen anything in my life! I don't even know this particular mgr's name.
