Airport Security review: Harassment

I had just arrived at Orlando international airport was dropped off by a friend, I came in through passenger check-in and I went straight to the bathroom. When I came out I was approached by an elderly gentleman and asked if I was flying out tonight and I said no I was flying out Saturday morning at 7:00 a.m. . He told me that I would have to leave the airport and come back at Saturday morning for my flight and proceeded to tell me that if I did not I would be trespassed. I don't feel I was treated appropriately and I should not have felt threatened by being trespassed in an airport by airport personnel because I came to the airport early. He could have just said you have to leave until you're scheduled flight. He did not have to mention that if I did not I would be trespassed. I looked at the man and I told him that I thought he was rude. And he laughed it up and said so then I'm rude hahaha. Very unprofessional and if there's some place higher I'm going to take this piece of crap of an employee of yours to a higher level of complaint. I felt harassed and I don't feel I should have felt that way.
