The line was long, and I waited half an hour to pick up the car.

Slow

This was the worst experience I've ever had. I kept getting harassed by the receptionists of Indian and Pakistani origin, while the car rental service kept shirking responsibilities. 1. They aggressively pushed for insurance, and when I declined, they started finding excuses. 2. They demanded my return flight ticket. When I showed them my itinerary from the airline, they claimed they couldn't read Chinese and refused service without a return ticket. When I called the rental service, they said they couldn’t resolve it. I had to barge into their manager's office, and only then their attitude changed and they processed my rental. 3. They claimed my Visa chip card wouldn’t work, and said if I used a magnetic stripe card, I’d need to buy full insurance, stating that the insurance from the rental service wasn't valid. When I called the service again, they still couldn't resolve it and instead suggested I contact the bank and mentioned we should have opted for a bigger rental company, implying they don't guarantee smaller ones. I had to barge into their manager's office again to get the issue resolved. Meanwhile, others in my group at a different counter had no issues. What problems can the rental service actually solve?

High pre-authorization amount, and won't allow the use of multiple credit cards

Got there, hired the smallest car available. All they had was 9 seater vans. Not suitable for our needs
