I'm coping to the fact that I've never paid for a ticket from Schiphol to Amsterdam Central....untill this last trip. I usually stay at an airport hotel in Schiphol when visiting Amsterdam. I am use to ticket takers on the trains (like in Belgium) and have always just waited for them to come through the carriage to buy a ticket. I'm thinking how am I never getting a ticket on the train between schiphol and Amsterdam Central!!?!?! Well. Turns out there are these card readers like ALL OVER in the main floor of the train area in Schiphol and you buy a ticket and scan the ticket then go to the platform, then scan again on you way out. It wasn't until this last time I was there that I figured that out. I hopped on a belgian train at schipol going to Central station and the ticket taker came and charged me the whole fare from Brussels for not having a ticket. So what should have been about a 4€ journey cost me 37€.
