The self-service ticketing kiosks at Paris Gare du Nord have horrible software usability.
You start on the welcome screen by tapping your preferred language (English or French). The second screen, guess what, asks you to chose you preferred language again.
And someone got paid to develop that second useless screen!
It’s a French thing made by a French company cally IER, guess what, Heathrow binned over 200 of them last year before thier sell by date expired because they coulld not cope with the airport.
