How many times have you heard it said that big businesses don't care about their customers? They exist to make money, and so long as the money keeps rolling in, everything is fine by them. They also have no reason whatsoever to do anything nice for anyone unless it benefits them in some way. And that's what makes this picture so special.
Somewhere, there is a Subway store manager who'd walked past lonely, starving homeless people down on their luck one too many times without being able to help them, and decided they'd had enough. And so, without caring what other people thought about it, or whether it would affect paid custom during those hours, they decided to do something wonderful. For two hours, once a week, they would open up the restaurant and feed the homeless for free. Kindness that seeks no reward is the purest form of kindness there is, and it's on display right here.
