Waited for 1.5 hrs to get served at Pickup desk

Had a very long wait of one and a half hours to get the keys at the airport. Firefly knows in advance when people are arriving to collect cars and how many. Why are arrangements not made to deal with customers in a timely manner? The customer service representative did not apologise for the wait. I had 3 young children and it was 11pm at night. Instead he had a go at trying ti confuse me into buying extra insurance.
