Ignorance......

Here is something that I have been thinking about for a few days....I work at a bank, and recently I had a customer come in, she started asking me random questions about our policies regarding asking people to remove hats, sunglasses, etc. when they come in so that we can see their faces and in turn properly identify them. She brought up the fact that we do not have any signs posted anywhere asking customers to remove these things before entering the bank and she questions how we are able to enforce having them remove the stuff without a sign posted. I informed her that even though there are no signs posted we are still allowed to ask that customers remove their hats and whatnot so that we can see them. Then she out of the blue says "well what about fundamentalist Muslims? What is your policy for them?" I'm thinking to myself "What???" So then she says "Well what do you do if a woman shows up wearing a Burka?" So at this point I am thinking "Ummm....what does that have to do with anything??" So I tell her that it has not been an issue and therefore we do not have a specific policy in place for that type of situation. So she proceeds to tell me that her sister-in-law was in bank recently and a woman in a Burka walked in and her sister was just freaked out the whole time.....so apparently to this customer a woman in a Burka=suicide bomber! I was just so shocked at the ignorance and racism coming from this lady. I had no idea what to say! I just basically reiterated that it has not been an issue and quickly walked away (I was letting her into her safe deposit box so I did not have to remain with her thankfully) I just thought what am I supposed to say in that kind of situation?? I'm like maybe we need a policy in place for how we deal with ignorant racist customers, I am sure we have all been in a situation where we have been shocked into silence by what someone has said, I think it would be helpful to have an appropriate response for this kind of thing. If I had said what I really wanted to say, which is somewhere along the lines of "just because a woman is in a Burka does not mean she is about to blow us all up, she is following her religious practices plain and simple and there is nothing wrong with that. The sight of a Burka does not automatically mean that evil is afoot, and I find your comments a little offensive" I probably would have gotten in trouble because I was at work and she was my customer. Plus let's be real here people...what would they have to gain by blowing up a bank in Utah of all places?? NOTHING!!! I just don't get people sometimes....
