A little bit like US Gas station I suppose?
I've since learned that you can use 00000 but that's not nearly as fun!
I've also grown accustomed to using 867-5309 (Jenny) when asked for a phone number to get grocery store "member" prices when I don't want to sign up. It works a charm.
Meanwhile, good luck getting gas or paying tolls in France without a French or other EU card.
French companies are also terrible at accepting non-French SEPA zone accounts. By law, they should accept all IBANs but their websites bork when it’s not French. Infuriating.
By the way, in Florida you don't even have to wonder about a credit card at the toll as it is Sunpass/pay by plate or cash only...
