Well, that's the pay off. When people come to my house, they don't refuse the beer I offer, even though it wouldn't be their norm.
There was a discussion about this on an American site that I post on, and a lot of people said they point blank refuse, and would just ask for a glass of water. Now I don't expect anyone to drink anything they don't [i:3g9wookw]actually [/i:3g9wookw]like, but when it's just a case of being offered something you deem to be inferior, to me that's borderline rudeness.
Maybe that's just an Irish thing, or the way I was brought up.
