I have a confession. I once was the old lady. Well sort of.
I was in C and this other guy A. We both ordered OJ. The FA brought beer and OJ and set them in the middle tray table. I waited a while for her to return. After a while she hadn't returned so I figured that OJ was the one I had ordered. So I drank it. A while later she returned with my OJ. It's been like 10 years and I'm still embarrassed.
But thanks for the laugh!
