If Dunkin' Donuts makes the simple and harmless mistake of forgetting to give you a receipt, don't go back in screaming at the employees, call them horrible racist slurs that would make Quentin Tarantino cringe, film it all on your iPhone, post the epic 8-minute rant on YouTube, and expect the world to be on your side. Guess what, it isn't. Congratulations, you are now the most awful person in the galaxy.
It's pretty safe to say that your budding career as a video spokesperson for the local restaurants and auto repair shops is over. I hope your super-duper uber-precious receipt was worth it.
