I booked a return trip Budva-Kotor online, then found out at Budva bus station that tickets need to be printed. Had to pay four euros for printing, but the driver did not give me back all the tickets. (It was printed on 4 different A4 sheets). On the return trip, the driver did not let me into the bus because I only had one ticket, but we were with two. I tried to explain the situation, that the sheet with the other ticket was taken by the driver, and that I did have the other ticket as well (I showed the PDF on my phone. The bus station employee refused to even try to understand and just repeated the words "other company" and "not my problem" until he angrily pounded on the check-in gate like a neanderthal. Ultimately, I had to pay three euros again for printing a ticket I had already paid for and had paid for to print out once before.
