They could say it, its not like they are going to hell.
Quite an interesting response though, the popular opinion that muslims would not say merry christmas, I wouldnt say ramadan mubarek to muslims I know, but they wouldnt expect me to, just as I wouldnt expect them to say merry xmas to me, I wasnt really sure on the etiquette. I have some good chats with my local shopkeeper Mohammed, so I shall bring this and see what he thinks of it too.
We have many good discussions on religion and every day things, he's my goto guy for asian related matters.
All due respect, if you want to have a chin wag with someone about religion then have one with someone with knowledge on rulings (Imam) not the local shopkeeper who "probably" sells alcohol, cigarettes and top shelf magazines
