The car rental system at Dubai Airport is really a piece of crap, At 3 AM there was a long line at the door, one customer took almost an hour to get their car, and there were only two staff members. By the time I got to the hotel it was 5 AM, and after lying down for a bit, it was already time to check out.🤣 With this level of service, don't even talk about East Asia. The car rental and return efficiency in Curaçao, South America is much higher.
