This story made me think of one of my pet hates. While the man's reaction, if true (it is Fox News after all) is kind of over the top, it is understandable.
It's odd. I have lived for over 20 years in a culture that routinely shares its food and I have absolutely no problems with that. Family style meals are fun, and I don't even think about it.
But it does drive me nuts when I am eating western meals and someone, not unlike my first wife, says something like "I don't want chips* with my dinner", but then goes on to "just try" some of mine.
"Hey, I ordered a full portion because I wanted to eat a full portion! Get your paws out of my plate!"
That marriage didn't last long!
Fortunately, I have lived most of my life in countries which don't have the USA's gun culture, so I haven't shot anyone - yet.
So, I wondered what others think.
*"chips" in the British sense. Although it could be anything.
