Efficiency is low and work is slow, waited a long time with only a few people in line. Seems like most French workers are like this. Their attitude is acceptable.

There was only one staff member at the Budget counter at the airport, often leading to queues of 7 or 8 people.

I rent cars in Europe for 200 days a year, and this car rental company is terrible. The counter clearly stated it was a deposit, but after returning the car and leaving Paris, they charged my credit card. When I asked the car rental company, they said it was for insurance. If I wanted insurance, wouldn't I have bought it at the counter? And they didn't even have my signature.

Communication through Google Translate with the staff was fairly smooth

The staff was very helpful and friendly.
