Something didn't ring up correctly, and the helper person had to come over and do some secret code stuff in order to get it all to finally go through. I didn't have my wits about me and I must have thought we took care of everything else because it was the last of my items. Anyway, so I grabbed my bags and left. I had made it all the way out to my car and began loading up when I realized that I hadn't paid for them. I walked back and had to tell them that I was an idiot and just walked out without paying.
