The car rental process at Munich Airport is indeed very busy. Europcar, SIXT, AVIS, and Hertz counters all have long lines. Europcar had five out of seven desks open, which was less than other companies who had all their counters open. However, a positive aspect was their numbered ticket system, so you don't have to stand in line after taking a number; you can browse nearby shops. This time, I waited nearly 40 minutes to get the car. I noticed that foreigners finished their process in just a few minutes; it took me less than ten minutes, but the groups of Chinese people in front of me took significantly longer, especially one group that took over half an hour.
