After a trip on bicycles to the North of Antwerp we returned on the Shuttle (water bus). The captain and the chief officer was selling tickets at the gangway. We left the bikes at the stern, and climbed to the upper deck. The youngest of us stood at the stairs and all the ascending tourists were asked to show tickets. Tourists dutifully showed. "Where are you from?". The tourists answered, for example "we are from Romania". "Oh, we are glad to see you in Russia!". I do not know how anyone, but we had fun.
