Yet another sign of creeping Islamicization in Britain?

The Daily Mail reports:

A Muslim store worker at Marks & Spencer refused to serve a customer buying a children’s book on biblical stories because she said it was “unclean”.
Sally Friday, a customer at a branch of one of the famous stores, felt publicly humiliated when she tried to pay for First Bible Stories as a gift for her young grandson.
When the grandmother put the book on the counter, the assistant refused to touch it, declared it was unclean.
… Conservative MP Philip Davies said the refusal to serve Mrs. Friday, 69, was “unacceptable” and “damaging” to community relations.
… Mrs. Friday said “Had this been a copy of the Koran I am confident any Christian person would be happy to do her job, and for this to happen in a Marks & Spencer of all places beggars belief.”
