Here's the backstory!
"My brother passed away July 7, 2012. His final wish in his will, if he left enough money, was that we have pizza and give the waiter or waitress a $500 tip. Aaron never had much money , and he didn't have enough to make this happen, so I started a website and took donations. On July 10 we were able to make his wish come true for the first time.
We think he just wanted to provide a random act of kindness and generosity for someone he thought was under appreciated; the kind of thing that would make a lasting impact they would never forget. If you want to keep his legacy going, please feel free to donate. So far we have collected over $1000 so we will definitely be doing this again, for another random waiter or waitress, very soon! Each time we have $500 we will do it again, even if that means going out to eat multiple times a day."
