Ahhh I think I finally got your point - that basically everything is confusing (as even my favorite porters can be untergärig). And I also learned that the Austrian Märzen is not exactly what I'd expect, so all in all an interesting beer thread :)

PS I wouldn't order a lager either. If I didn't care what they have (very rarely) I'd order "a beer" and live with it, or otherwise I'd ask for the choices.
