Muslim bookstore employee refuses to touch "unclean" Bible story book

From the Daily Express:

A MUSLIM store worker refused to serve a customer buying a children’s book on Christianity because she said it was “unclean”.

Shopper Sally Friday felt publicly humiliated at a branch of Marks & Spencer when she tried to pay for First Bible Stories as a gift for her young grandson.

When she put the book on the check-out counter, the young assistant refused to touch it, declared it was unclean and summoned another member of staff to serve instead.

Mrs Friday said her trip to the sales in Reading, Berks, with her daughter had been ruined.

“I went to the till and heard the girl say it was unclean and then she got someone else to serve me,” said Mrs Friday.

“At first I wasn’t sure what was going on and then I realised she was wearing a headdress and I clicked that the title of the book had Bible in it. I felt very humiliated and immediately left the store.”

How could she have felt humiliated? That emotion only applies to one set of people.
