Allied Security review: My rights.

A Allied Security officer at the Nashville TN. Station walked up to me to check my ticket, all was good, then asked me if I had a nife, I said yes, he ask to see it, and then confiscated it, I chuckled thinking he was kidding around, but no, he took it and put it in his pocket. There is no sign on the entrance door saying no weapons allowed. So it never came to mind I was breaking a rule at point of entrance. I have no argument about it. I just said I did not know that. Next day I asked his name so I can call corporate to try and get it back cause it has sentimental family value to it. As of asking his name he refused to give it and said he will call the cops for me threatening him, them asked for my ticket then kept it and said I had to leave. I said I think I'll wait for costumer service to open at 7am to get my ticket back because I did not threaten you. I only asked your name dude. He said he is writing a report on me and will have me removed from premises. Costumer service opens up, hands me my ticket back and said your here to catch a bus, so have a seat n wait for your bus an have a good day.
Wow! That security guard went to his desk by the entrance pouting. Sorry but, lol!
I would like to retrieve my precious nife back, that my pappy gave to me years ago. O_o'
I was of no threat to no one just cause I carry a nife. Good god people!? @[protected]@'
Thanks for any common understandings.
