This item from Reuters caught my eye:

The Irish flag is flying again at an Irish pub in northeast Florida, where city officials suspended a ban on flying non-U.S. flags just in time for St. Patrick’s Day celebrations on March 17.
[…]
The sisters said they had flown the green, white and orange Irish flag alongside the American flag in front of their pub for eight years, and were shocked when code enforcement officers gave them a citation on February 20. It said they had 24 hours to “cease display of flags other than American flag.”
The obscure ordinance was passed in the 1990s as part of a previous administration’s attempt to clean up an unsightly commercial area, according to Marks. 
 

Emphasis mine. How much do you want to bet that “unsightly commercial area” translates to the Mexican/Cuban side of town?
