After Even Living Nearby, I Never Knew Until Now

Apparently, the SF "neighborhood" known as the Tenderloin is named so because back in the day the police were paid so much more to cover its mean streets that they could afford a tenderloin sandwich.

I always thought it had something to do with the tender young boys and girls and bois who are often calling for companionship. Or the way that drugz can make your teeth and gums kind of tender.
