Nothing wrong with it.
It's daft as fuck. Nobody needs to drink it. Adjusting to every other culture and belief is a favourite among a lot though. Urgh.
It's not about adjusting your culture to theirs, it's simply finding a way of meeting theirs but also it doesn't get in the way of the dominant culture. Making alcohol free drinks available is clearly not repressing anyone's culture. It's simply an option there for someone to exercise, if they wish.
It's hardly fucking ramming theirs beliefs down your fucking throat, is it?
It's the principle of it, more than anything. Changing ways to adhere to conservative/other beliefs. The champagne already was an option for someone to excersise. Simply no need to change anything.
