Krakow, over 20 years ago. Ancient Soviet trams and very noisy uneven track.
We got accosted by a ticket inspector who started to try to drag us off the tram even though we had valid tickets (which were absurdly cheap). Hardly anybody spoke English there in those days and we spoke no Polish. We just ignored her as we didn't know what to do. Later we deciphered what she had been gesticulating about - we were supposed to have bought tickets for our rather large backpacks!
