Dollar General review: Management frances

I was in line to check out, manager Frances was checking 2 gentlemen out. And she told the one man to remove his hat when entering store. But others walked in didn't tell them. Then they got upset asking her this has never been a problem there wearing a hat. She was rude to them. The 2 men were so angry with her they just left their stuff. I've been shopping in that store for 13 years. Never had heard such a thing. But the question is... Are you aloud to wear a hat in the store? Because my husband and I my son always were a hat in there. Never once have been told that. Her attitude was terrible towards them.
