All the car rental companies are in one building next to the airport. You handle the paperwork on the first floor and then go to the second floor for the cars. The whole process was quite fast, and the staff were very professional. But! I booked a Mercedes! A Mercedes! And they gave me a Citroen!! Besides going to Prague, I was going to Germany! I specifically booked a German car! And you give me a French car!! Also, the entire parking lot is 80% full of German cars, mainly Mercedes! But they gave me a Citroen! Unhappy, I went back to the counter to negotiate again, but the staff said that the cars had been pre-arranged and couldn't be changed now! This isn't the first time this has happened! Last October, I went to Morocco and booked a Jeep Wrangler, but they gave me an Audi sedan!!! I wanted an off-road vehicle for the desert! And you give me a sedan! What does that mean? I specifically chose an off-road vehicle! Specifically chose the Jeep Wrangler! You didn't give me a Jeep Wrangler! Didn't even give me an off-road vehicle! Do you think car renters are people with no requirements, and any car will do? A car is a very important part of the journey! Can you not be so arbitrary? Yes, you'll say the terms state that they may substitute a similar-class car, I understand! That's why I didn't complain last year. But now it's the same situation again! I feel like choosing a car model while booking is meaningless! Because you never know what they'll give you when you get there!!! And at that moment, you just have to take what you can get!
