2ed September I travelled from Delft to Rotterdam, then I took an international train inside the station, I tried to check out at the pole but it's a wrong pole(it's about an extra fee for going to the airport), but when I aware of this I'm not in the Netherlands.
Tomorrow I'm going to get back to Rotterdam, and I wonder what should I do after I get off, can I check out directly or I should re-check in? And in this case can I apply for the refund of the deposit?
