it looks like you guys miss the point. You are focusing on the hijab only, and come to the conclusion that this discriminates muslims...
but the Bank policy states that any head covering unacceptable. "...no Muslim woman wearing a head scarf, no Sikh man wearing a turban, no Jewish man wearing a yarmulke, no cancer survivor wearing a scarf, no Amish woman wearing a bonnet, and no blind person wearing sunglasses may enter a Navy Federal Credit Union branch nationwide.
So, yes King Edshel, they most likely would ask “one of those guys with black hats to remove it“ as well...
There is no need to resent about hijab only.
