Here in Maine, the bank my mother uses once had a sign on the door prohibiting hats.
The few times I went in there with my mother I was wearing a baseball cap, and I kept it on my head. No one said anything. If they had, I would have told them to go to hell.
While on another visit to the bank, I told my sister, “What happens if a woman undergoing chemo-therapy enters the bank wearing a head scarf to cover her hair loss? Are they going to tell her to remove it? What if a Muslim woman comes in wearing a scarf over her head? Are they going to tell her to take it off? There’s going to be a big stink raised and a lawsuit!”
It wasn’t long before those signs were removed.
Meanwhile, bank robberies in Maine are extremely rare. In my area of Maine, where I’ve been for over 20 years, I can’t recall there ever being a bank robbery.
