Not sure where to post this, so here we are.

Once while out at lunch, my father mentioned a personal financial matter is a rather loud voice. I said, “Dad, could you lower your voice? We’re in public.” He just stared at me for a few seconds before resuming the conversation at the same volume.

Another time, while using public access computers, there was a man talking loudly on his phone. A woman at a computer said, “Sir, can you lower your voice? You’re talking right in my ear.” The man stared at her for a few seconds before resuming his phone conversation at the same volume.

A third time, a woman was watching a loud video (that had no inappropriate content) on a public access computer at a high volume. A man asked her to turn the volume down. She ignored him.

What’s going on? The hope is that the loud people would apologize for the disturbance and lower the volume. Instead, they stare the accuser down and/or ignore them. Why can’t people be polite and considerate?
