Average. The staff member handling the car pickup had a heavy Indian accent, making it hard to understand him, and he became a bit impatient later. I rented a Prado but received a Suzuki MUX instead.

There was hardly any queue, quite convenient.

The staff were friendly and patient, and the process was very efficient.

After exiting the arrivals, the car rental company is on the left with clear signs. The Budget counter was unattended, and there was a sign directing us to the Avis counter. A lady there assisted us professionally and explained the benefits of buying insurance. I mentioned that I had already purchased QEEQ's super insurance. She then handed me the keys and directed me to the parking slot to pick up the car myself.

Budget service at the airport is ok and I believe Hertz staff help out in the pick when the Budget staff were not available. The waiting time is about 45mins.
