It sometimes happens that a bunch of French kids or teens will get onto one of the little tour boats which go up and down the Rhine river. When that happens, the other passengers will invariably get off the boat and demand their money back, and get it.
Wow, that sounds similar to the nuisance kids In Brasil, who will block traffic to beg for money from the blocked cars. Then they go and buy beer for their parties on the beach with the money.
Are these kids doing the same thing to the passengers?
