I found most of the airport employees to be very rude!! Very impatient and completely unknowledgeable. Few food options, hamburgers, pizza, and a Irish restaurant, oh yea you can get a hotdog. Most of these places are repetitive throughout the airport.
Besides the lack of decent people that work at these or places, the airport has very low ceilings and tight walkways throughout the various terminals.
While they can improve on the structure, not sure how you can teach their employees manners as well as common sense!
