If fact, I would *hope* that someone would step in with the correct information if I was being told something that was not true. I think that if I had been that woman and a nice stranger interrupted politely and gave me information that made me feel better and more confident about my purchase, I would have been very appreciative. There is a big difference between being nosy, butting in, and being a know-it-all...and politely assisting a fellow brother or sister.
