I was the victim of dcc during my shore excursion from Rostock to Berlin. We stopped at a service area on the autobahn and I purchased about 7 euro worth of stuff. The dragon lady type clerk, surely East German type, had the credit card terminal not on the counter, dipped my card, did not ask me to sign and handed me a receipt. It was only when I got on the coach that I realized I had been ripped off with the statement I was offered the opportunity to pay in local currency. It must have cost me about 40 or so cents.
I will orf course be disputing the charge when I come home and hope the bank has the good sense to charge it back to this scum of a merchant. This spreading cancer must be stopped in its tracks and I will not allow myself to be treated like a sucker in this manner. However, most likely the bank will just credit me the 40 or so cents and not charge it back and penalize the piece of garbage merchant.
