I walked in to find no security guard at desk so I proceeded to check in area which is right next to desk. I then hear this man screaming at me to remain where I am and not to go any further, it was the security guard. He was yelling at me saying "don't you know how to read signs" there was a sign to check in and that's what I thought I was doing. Apparently they need to inspect your bag and ask questions which I understand. He proceeded to read me the riot act and I stated I did not realize I needed to stop as soon as you enter. I said to him he did not to be so rude and that I had made a mistake and then he told me to leave the premises. He stated he did not need to listen to my excuse and therefore to just leave. I couldn't believe this security rent a cop is allowed to treat tax paying Americans this way. I asked to speak to someone hire up and he stated he pointed to a picture of President Trump and VP Pence. Then when I looked online to where I can write a complaint and see this man actually recently assaulted an elderly disabled man. Wow, not sure how this man still has a job but after seeing that I guess I got off easy. Just don't understand why my taxes are paying for this barbarians job. This is just not ok.
