I got the bus from Greece into Albania and it was, err, quite the experience! We stopped at the border for passport checks and to use the toilets. My boyfriend told me not to use the toilets but to go in the bushes and dear god, I wish I had listened. There was shit everywhere. On the floors, in the sinks, up the walls, just everywhere.
A few of the passengers didn't have papers to travel between Greece and Albania so the driver let them out a few hundred metres before the border so they could cross through the woods then picked them up on the other side! The scariest part was when they decided to change drivers on a steep mountain road without stopping the bus. Something went wrong and the bus suddenly swerved towards the edge of the cliff. One driver ended up on his arse in the aisle while the other grabbed desperately for the steering wheel to stop us all plunging to our deaths. I'd still go back though 😁
