I don't know.
But mostly I feel the brute embrace of the BNP coming on and so I will resist it.
I've had a quick skim to see what the muslim poster who I happen to agree with on almost everything, mostly non-muslim-related, had to say but I haven't seen her.
But then I bailed at page 6.
Maybe that was cowardly of me, but I confess, that's me all over. I'm not going to name her because that might embarrass her, but I hope by some celestial means she knows who she is and that we'd probably agree 
Like others have said, a warning at the till would be handy.
But supermarkets expect customers to suck it up when the checkout person is under drinking age or the customer is under 25, entirely for their convenience because serving alcohol by underage people or to underage people is disastrous for them, so why not here?
I only wonder how the person would handle other offensive products? Or whether handling but not partaking is banned. I guess others have asked that.
What happens with teetotallers, or vegetarians or Catholics who object to the use of condoms?
A muslim customer services person in Sainsbury's once thanked me profusely for telling her that my bag contained pork when I returned it.
She thought I was telling her so she didn't have to handle it.
The religious aspect didn't cross my mind. I'd mentioned it because the meat was rotten (some kind of hideous stock control mistake) not because it was pork.
I don't know what I think about that. I was slightly offended, but not that much. And she was grateful.
We've lived to celebrate another Christmas.
