Wrongfully terminated after one day of orientation - Security Guard CNA Corporation Employee Review

Good morning! I wanted to write a post on my experience with the company Center for Naval Analyses | National Security Analysis (CNA) CNA Corporation. I was hired for a part time position on the weekends to do security and attended my orientation and was terminated the following day. I received a call stating that I was not a great fit for the company because I did not eat lunch with them due to me having to go back to my full time job. They also stated that I did not participate in the orientation and from my understanding during an orientation you are listening... I feel as though I was wrongfully terminated because I asked was it ok for me leave and I was told yes by the Orientation instructor. I never experienced anything like this in my life. I'm not sure if this is the way that this company normally handles things but I was extremely disappointed.
