He is quite useless, and the quickest means of getting free is to say that you have come to the city for no other purpose than to pay extravagantly for everything.

The guides outside the Ryks Museum who offer to point out the beauties of the pictures are less persistent.

It would seem as if they were aware of the unsoundness of their case.
