A colleague was in Morrisons recently when the muslim till operator asked about his H4H wrist band. When it was explained that it was H4H, a charity to support the troops, the muslim till operator refused to serve him.
The manager was duly called and explained that the till operator had every right to refuse service. The rest of the queing patrons all left in disgust, as did the queing public on adjoining till ques.
They simply left their shopping and went elsewhere.
So will I.
