Ljubljana to Hallstatt Round Trip

First of all, the store is hard to find; it's near the departure gate, next to a small post office. Getting the car was quick. The car was an Opel Corsa with 60,000 km on it. However, that night I found out that the headlights weren't working; the left one was completely out, and the right one was dim. Without streetlights in the mountains, it was impossible to drive. When I called the store, they said I was too far to swap or fix the car. Come on, if I were close, why would I rent a car? What a lame excuse. When returning the car, first about the garage: There are two gates with two slopes, one for taking a ticket and one for scanning it. The second gate is an employee entrance which doesn't work for us. Unaware, I got out to inspect, ensuring the handbrake was on and the car was stable. To my surprise, it started rolling down the steep slope. Weighing only 100 pounds, I couldn't stop it. Thankfully, I was quick and pulled the handbrake just in time; otherwise, the car would have crashed into the barrier. Now stuck on the slope, the car couldn't reverse uphill due to its small engine. Panicked, I ran to the store for help. They immediately asked if I had entered the wrong entrance and if the car was undamaged, showing they were aware of the trap. They had an employee swiped his card and drove it in effortlessly. Why couldn't they help initially? During the final inspection, they found a 2cm x 1cm scratch on the rim and blamed me for it, even though I didn't check at pickup. I reluctantly said I had driven carefully. The inspector said, 'You did well, just a small issue, 20 euros.' What does that imply? I give three stars as I acknowledge some of my mistakes but hope my experience helps others avoid such pitfalls.
