"Stopovers: On my return trip while stopping over at Zurich I had to transfer to another gate and go through security check again. I had bought some wine at Stuttgart airport, and although it was shrink wrapped, propoerly sealed at the duty free shop in Stuttgart and clearly stated that it could be taken on subsequent flights the same day, and had a receipt with it, I was not allowed to keep it, as the shrink wrap apparently didn't have the correct markings on it. This seems ridiculous, there should be a single, international, uniform way of shrink wrapping at all airports."
