It was a horrible and took 2 hours for pickup

Terrible experience as it took more than 2 hours to pick up the car. Only one person on the counter and two customers in front of me in the line. My turn came after 90 minutes. They came up with another addition of $46 to add to our own insurance and which was not listed when we had booked the rental. When we did the drop off we had to wait more than 30 mins for the shuttle. It is supposed to be pickup within 15 mins but the person on the first shuttle did not take us even though he was going to airport but not for our Airlines. He told us the next driver will take us for our airline which makes no sense. The second driver also tried to go the same that next driver will take you for United but we had to tell him we couldn’t wait another 15 mins so please drop us.
