Experienced a touch of jingoism heading for the Denmark ferry in Puttgarden no so long ago. In convoy with 10 or so fast moving cars, several different nationalities, all of which, save the Germans, got pulled over at the next lay-by. The green suited, gun wearing traffic cop waived his countrymen through and the rest of us got taken to a road side hut (built for purpose) to see the photographic evidence. I tried to protest and was met with a gun out of holster (probably disgusted at my poor German), not pointing at me, but in hand and very threatening.
I only had large denomination Krone and no Euros and had no choice but to leave them with the equivalent of about £300. Give them their due though, a week or so later, a letter arrived at the house in Sweden, in the middle of nowhere..., with my change and a thank you note!
