Again, another person who missed the point.

What rules? So muslim women going into shops wearing veils has been a serious problem up until now has it? Considering the muslim community is accused of being too insular, and that they generally only shop in muslim owned shops etc, it therefore shouldn't be a problem for you should it, because you're never likely to see a muslim lady wearing a veil in your bank.

Stop looking for an excuse to discriminate against someone. Grow some balls, and just come out and say you don't like people wearing alternative clothing!
