TSA roll

I was at SFO (airport) about to go through security.  I took my computer out and put it in a bin, put my shoes and belt out, and in a bin, and made small talk with the security agent, who was very nice.  After I completed putting everything in the bins, and put my backpack on the x-ray belt, I turned around and proceeded to walk toward the body scanner rolling my suitcase behind me.  The nice agent started laughing, so I realized what I was doing and I corrected myself, after which the agent proceeded to tell all the other agents to keep an eye on me.
