Oh, yes: What about pumps and taps? I read something about bars (or pubs, if you prefer) using gas to pump the beer. That doesn't sound like any way to treat a good beverage (or any kind of food). Does this mean that it's better to drink bottled beer or ale, unless the bar has a proper pump? (I could be wrong, but I think you'd have to walk many a mile in Germany to find a bar that had proper pumps.)
