True story:
Many years ago, I davened regularly in a largish shule. My makom was in the front. In the row in front of me were several talkers, who happened to be machers in the shule. On one Shabbat, they were talking particularly loudly. I turned around (so I was not facing them), and shushed them quietly. One of the men took exception to this, and berated me right then and there.
I changed seats the next Shabbat, and I never did move back to that spot.
Right before Rosh Hashana that year, he came up to me, apologized, and asked mechila for embarrassing me the way he did. He said he realized that he was wrong, and that he had been working on not talking during davening. He even invited me to move back to the original seat. Of course, I forgave him, but I didn’t move back to the old seat.
And by the way, to 1: There is a conservative shule down the street from where I daven in the mornings – they have well attended minyanim 3 times a day, every day. So yes, many go only 3 times a year, but there are some who go 3 times a day.
