It started innocently enough. A twitter user, housebound with a foot infection, simply lamented the fact that his condition meant he wouldn't be able to enjoy a burger at his favourite burger joint on #NationalBurgerDay.

Because it's the normal thing to do in 2014, he put out a plea to the Twittersphere for someone to bring him one.
.@byronhamburgers Confined to house w foot infection-can't walk. Need healing of burger. Anyone care to bring me one? #nationalburgerday
The folks at Byron Burger noted the plea and offered their sympathies, but admitted that they didn't offer a delivery service. So it looked like John's 'Burger Wish' would remain just that...
@johnbdivadivine We don't deliver, but I hope some kind soul comes to your rescue. Get well soon!
But just when it seemed all was lost, London Taxi company, Addison Lee stepped in with a solution...
We hear you @johnbdivadivine We’ll come and get you and save your #NationalBurgerDay! Quick trip to @byronhamburgers ? #RandomAddOfKindness
@AddisonLeeCabs @byronhamburgers How much from SE15 to my nearest Byron?
And they wouldn't even accept payment.
Put your money away @johnbdivadivine The car’s on us! @byronhamburgers are you going to help make it a #nationalburgerday to remember?
Picking up on the good vibes, Byron Burgers decided they'd help out with this #RandomActOfKindness.
@AddisonLeeCabs @johnbdivadivine Greenwich is your nearest restaurant John. What do you fancy???
@byronhamburgers @AddisonLeeCabs Haha! A Byron burger and onion rings with some garlic mayo. And a glass of water please. (OHMIGOD)
@johnbdivadivine Your wish is our command. @AddisonLeeCabs, when can you be there for?
So Addison Lee got ready to send a car...
Just grabbing the keys @johnbdivadivine DM your address and we’ll be round shortly. @byronhamburgers fire up the grill #NationalBurgerDay
...while Byron Burgers made sure they had John's order just right.
@johnbdivadivine @AddisonLeeCabs You want that Byron cooked medium? :-)
@byronhamburgers @AddisonLeeCabs Yes please, that would be just right!
Car is on it’s way @byronhamburgers @johnbdivadivine will be with you within the hour! Happy #NationalBurgerDay
And so, with the help of a burger bar and a taxi company, wishes were granted, and John got his burger on #NationalBurgerDay after all!
@AddisonLeeCabs @byronhamburgers happy #nationalburgerday to all! And mega thanks to @byronhamburgers and @AddisonLeeCabs !!!
