Liège

Liège-Guillemins railway station, waiting for my trains back to Chastre. This was probably my worst Belgian train experience. The Belgian rail website gave me an itinerary with Liège-Ottignies-Chastre, with the cryptic message "you may need two tickets". The machine gave me one. I passed Gembloux - next station Ottignies - and the conductor came, saw my ticket and dressed me down very loudly, that I should got off in Gembloux. I showed him the app and he said it didn't matter, I should have got off in Gembloux!! That otherwise I needed two tickets. I asked where I could get another ticket, and he shouted back it was TOO LATE but to remember it for next time. Still not sure where or how I should have got the second ticket
