re: Is there any place that people have less self-awareness than grocery stores?

There are a lot of unpleasant coincidental incidences in grocery stores. Women ages 40-80 are completely without any spatial aptitude. That same demographic is also unbelievably rude and seemingly entitled while in a grocery store. I’m not sure women comprehend the concept of sharing. Men, typically, are the most efficient and polite shoppers. There are a few “aloof” outliers, but the fact remains. Any demographic ages 70-Up are a total disaster in a store.
