How many times can you get scammed in Paris? Well, how many times do you blink your eyes? How many steps can you take? Think of a number between 1000 and 100000000.
Seasoned travelers we are, we were nearly scammed in Paris but avoided any loss and learned, nearly, from the experience.
Having just arrived at Charles de Gualle and made our way to Gard du Nord we were momentarily confused in getting from the train station to the tube station. Fortunately (not) there was a "gentleman" to "help" us. By "help" our guide meant to purchase our tickets then suggest that we pay him back in cash and, surprise, a local ATM was within reach. Once we realized the scam we was on we played along and went to the ATM but kept on walking and down a nearby Metro entrance. Once underground we shed our coats, switched bags in case the moron was following us and purchased tickets to out destination.
Who knows what would have happened at the ATM? The word to the wary is that NOBODY is interested in helping you in Paris. Just say No.
