Why U.S. Mail Isn’t Delivered on Sunday
In case you needed further proof that the separation of church and state in America is not even close to enforced:
“Until 1912, mail was delivered 7 days a week. As the postal service grew in popularity and usage in the 1800s, local religious leaders were noticing a decline in Sunday morning church attendance due to local post offices doubling as gathering places. These leaders appealed to the government to intervene and close post offices on Sundays.”
