Sunday and evening hours: You can bank on it
Chicago — the town Billy Sunday couldn't shut down — always had a tough time keeping the Christian sabbath free of trade. An 1845 Chicago law prohibited taverns from opening on Sundays, but the ban was unpopular with Irish and German immigrants, according to the Encyclopedia of Chicago. When Mayor Levi Boone tried to enforce the law in 1855, it led to the Lager Beer Riot.
Well, there was more to the riot than the schedule issue, but it's interesting to see this take on it.
