Manners?

I'm content, if not happy, that Muslims have a world-view which differs from mine. But when they seek to impose that world-view on me in my own back yard as it were, they go too far.  Islam forbids the consumption of alcohol. OK, I have no problem with that, but when they refuse to sit down and have a meal with me if there is alcohol on the table, that isn't on.  This is what happened in the recent visit of the Iranian President to Paris where an official dinner had to be cancelled because the French refused to take wine off the menu.  This was in France, remember - the expression "when in Rome..." springs to mind.
