They breed for money and negotiate with drivers. Keep in mind that when buying tickets online, when you arrive at the station, you will be told that you still have to pay 2 euros per person for printing tickets, when we said that nothing about printing is written, they said that you still have to pay the "station service fee", which is not mentioned anywhere. Otherwise, they won't let us board. In fact, it's just an additional divorce for money.
After my friend and I decided not to pay anything and go to the nearest stop on the way west and take a bus there - the bus to Dubrovnik from Jadran Express just drove past and the driver waved at us, although there was enough time to stop. I attached a picture of him leaving us. As a result, we missed the trip to Croatia because of this. Flixbus support said that they could not make a refund, because tickets for the company's third-party. I will write a statement to the local authorities.
