When our language skills aren't very good, it's important to rely on the service quality and awareness of the rental staff. For this location, I felt the service person was just average. He was a middle-aged man who seemed eager to finish up by 6 PM. We arrived at 6 PM after getting our luggage and passing through customs, and he seemed a bit impatient. He also recommended the 'prepaid full tank option,' which we considered and agreed to, so we can't really blame him for that. Additionally, we showed him our three-year international driver's license obtained through the rental company, but he didn't recognize it and insisted on using their company's translation service. Fortunately, I had the foresight to apply for their translation service and had it printed out, which saved us a lot of trouble. Otherwise, it would have been a real mess (which made us quite unhappy and frustrated).
