Session No. 91 is hostet by Belgian Smaaak. Hence the topic. Because of a delayed train to Paris we got free Thalys train vouchers from the Sncf. Booking those tickets from the one and only Sncf office in Cologne isn't that easy. You have to ring them, send in the vouchers, talk to them again, reconfirm the booking. Basically you have to jump some pretty big loops to get on the train. Three long phone call later we finally had the tickets and some weeks later we were ready to start our trip to Brussels.
