If I need to leave the station paid area for a short period, to visit the restroom for example, what can I do?

1. Passengers holding single journey tickets may ask for a refund if they wish to leave the paid area within five minutes of entering, without the fact of travel. Data on electronic tickets, too, can be adjusted accordingly. Exit through the service gates. To reenter, a new ticket or electronic payment must be made.
2. Passengers who need to exit or enter the paid areas briefly, e.g. for the restroom or other reasonable intentions, may ask for assistance at the information counter and do so through the service gates, without occurring extra payment.
