At least two people in the newsroom were surprised at the results of our online poll about the Post Office's suggestion of eliminating one day a week of mail delivery.
Anyway, I was looking up some information about the Postal Service for another purpose and I found something interesting on Wikipedia. (Wikipedia is not infallible, of course, but I did a search and found confirmation at a few other sites.)
Until 1912, post offices were open seven days a week. Because post offices were often community gathering places, religious leaders thought that closing them on Sunday might encourage people to go to church instead, and they lobbied the government to drop Sunday mail service.
I'd never heard that before and thought it was worth mentioning.
