I used a Euronet ATM in Berlin yesterday. Ended up with 82 Euro cents per US dollar. Not good at all, but I needed the cash to pay Deutsche Post, which inexplicably doesn't take cards. Berlin was a revelation: we needed cash numerous places there. Have not really needed cash in England, Scotland, Ireland, Spain, Belgium, the Netherlands or France. Odd.
German trains also turned out to be pretty much total crap, another surprise as I expected both promptness and cleanliness, getting neither. Vodafone plan purchased in Netherlands was useless for calling in Berlin, and the German Vodafone people wouldn't help as they claimed Vodafone Netherlands to be an unrelated entity. Ha freaking ha.
Love Berlin nonetheless. So much to do and see. Not many foreign tourists there yet, either.
