The Germans really never had gotten their heads round the concept of sandwiches. The best that could be said for the analogs you were able to buy on the continent was that they were bound to be a lot healthier than the real thing. Beyond that, however, they were just the sort of thing one would expect from a people known all over the world for their lack of humour and the fact that they loved that guy of "Baywatch".
The things they sold under the pretence of being sandwiches were soggy and nearly tasteless, a combination of watery tomato, soggy lettuce and phlegm masquerading as boiled egg. Worst of all, there was not the slightest hint of mayonaise on it. John peeled the pieces of bread apart to examine it further. There, indeed, seemed not to be any greasy base to it, although somebody might have thought of margarine somewhere in the vicinity.
