The reactions in this video are so genuine and sincere.  Andrew Hale who's known for doing internet pranks and video experiments, flipped the script and secretly paid for peoples groceries right before they checked out, then filmed their reactions.  He never once reveals himself to the unsuspecting costumers and even lets the store employees 'sort of' take credit for the good deeds.

Seeing their reactions to this random act of kindness put a big smile on my face this morning.  Can you imagine if we all did something like this even one time a year.  It inspired me to do something special for a stranger this holiday season.
