Is AUTHOR wrong in the post ? POST : Just to let you know how long this has bothered me, it's been about 4 months and I STILL think about this situation to this day. 

One day I was shopping at a supermarket and when I went to checkout, I stood in line behind this elderly woman. We were both in the "less than 10 items" line but apparently, since it was nearing closing, they closed the line and told us to redirect to the other available cashiers. 

So naturally, I went to the next shortest line right beside this checkout. It turns out that the elderly woman followed suit and lined up behind me. 

However, she then proceeded to ask me if we could switch places. Normally, since I'm a pretty passive person, I probably would've conceded, but that day, I was in a rush and I already had a friend waiting for me for over 10 minutes. So I told her that I couldn't that I promised to be "as fast as I could" with bagging my stuff and leaving. She then said, kind of passive-aggressively that the speed at which I checkout is not dependent on me but rather the cashier. And then she remarked that the fact that I was ahead of her in this line, it was if I was cutting in front HER. 

I didn't know what to do next but I didn't want to give up my spot so I just shrugged and stayed in line. She then moved to a different line, in frustration I imagine. 

In my mind, I justify my choice by telling myself that I was in the right because this was a NEW LINE and she didn't have to follow me; there were other cashiers. And since in new lines, no matter what order you were in previously, the old positioning doesn't apply. But she was elderly though...

So AITA?
