NOT HAPPY! Booked a table for my 21st in the Cargo Lounge but had some of my guests refused entry due to the shoes they were wearing (Air Max's) or for not having a collared shirt on. After reviewing the email I received when I had booked it clearly did not specify particular shoes not being aloud or collared shirts being a necessity. I showed security the email and I was treated rudely and disrespectfully resulting in them losing the business of me and my 25 guests! Terrible!
