We thought it was really funny, when our hosts told us, that they wanted to drive to Luxemburg to fill up the tank of the car, but when we saw the prices there, we really understood.
It is funny, that this town is called Wasserbillig, Water cheap. It's not the water, that my hosts want to buy here, but the petrol, which is about 30 cents cheaper than in Germany. Because the petrol is so much cheaper, there is one street with many many petrol stations.
We also were in a shop to buy some chocolate and other things that are cheaper there than in Germany.
Here is another photo of Wasserbillig and of the 'border' to Germany.
