Because there the lady in the service very surprised me with her high personal culture and great understanding of the customer, that's why I chose this company and not another at the airport in Dortmund, the full professionalism of the lady helped me a lot in making a rental decision, so far nowhere I have met with such a high personal culture of a rental employee, and I fly 80 times a year around the world. Thanks again to the lady for a very high quality service.Gregor Jablonski.
