Your anecdote is weird. I've been paying my Navigo pass and equivalent for ~20 years and rode thousands of times in the metro, bus, tram, Noctilien, Citadin and RER, and I have never encountered such situation. I've lived intramuros (mostly on line 13) and in the suburbs (RER B) which are both renowned as being the worst in Ile de France, I've commuted both as a student and as a worker in almost all directions (Saint Denis, Massy, 13ieme, 18ieme, 20ieme...).
