It took over 2 hours from the start of waiting in line to the end of the process, even though there were fewer than 10 customers ahead of me. There were four service counters, but the staff were extremely slow. They moved slowly even when walking or copying documents. Additionally, two of the counters’ staff took a half-hour break to go to the restroom or rest, wasting customers' valuable time. A car rental company should process things quickly since customers who just landed usually have urgent matters to attend to. The efficiency and capability of the service are simply unbelievable.
