I presume he would have stayed at a hotel in Denmark, and gone out for dinner, and spent money on all sorts of things... money which is now going elsewhere.

There is much speculation in Germany about how this could harm the Danish tourist industry... there are whole resorts on the West Coast which are almost entirely dependent on German tourists, and there is already a lot of talk of "not going there again if I have to queue at the border"

I think Denmark has shot itself in the foot!
