Staff were great, car was great, the queue to pick up the car was long, and only 2 or 3 staff taking the bookings. Surely the rental company knows exactly how many cars are booked per flight, and can therefore have sufficient staff on hand to deal with the influx. We had prebooked and prepaid, so only had to produce licence and sign off, but still had to wait in queue with others who either hadn't booked at all, or had booked and not paid. It was a long drawn out affair.
