Why would you ever do that? I went drinking with a German once and he wouldn't shut the fuck up about how great beer is in Germany because they only use four ingredients and how Miller High Life (the American equivalent of Stella) tasted awful. We were at a fantastic bar as well (that had 100s of rotating selections of beer from small breweries all over the US) and he would only order Beck's.
I can't imagine going to a country where everyone would let you know that Carlsberg tastes like piss and Gammel Dansk is inferior to Jagermeister every second you are there.
