One of the ultimate examples of "corporate solutions for government problems" is the Starbucks bathroom.

American cities are particularly lacking public toilets, and rather than deal with that directly, lawmakers have been content to let Starbucks and other chains take on the duty. (Yes, I said duty.)

New York's former mayor Michael Bloomberg famously deflected public pressure to address the restroom issue 20 years ago, quipping that "there's enough Starbucks that'll let you use the bathroom." (Then he proceeded to tackle the real scourge of Gotham known as Big Soda... but that's a rant for another day.)
