5 Things to remember when riding the metro, RER, etc. How frustrating can it be when you get a fine for something you didn't even know about? When most visitors ride for the first time, they get the ticket that seems right to them and hopefully get to their destination. That's until - yeah. They're unable to exit the RER because the ticket they purchased wasn't valid. And later, they get the hefty fine for throwing their paper ticket away earlier. Anyways, here are 5 tips to not end up in a situation like that one. 1. Always keep your ticket with you until you exit the station. Very simple. If a fare inspector comes, just show them your ticket and you're good. And why not keep your paper ticket as a souvenir?
