Movie: Yes Man (2008)
You've been here before. Maybe you wanted to go to lunch with a friend but couldn't afford it, so they spotted you. Or maybe you had broken up with someone, and a close friend stayed and ate ice cream with you until you could no longer cry. It's always nice to give someone a helping hand, even if you don't know them, because you never know what they've been through.
Plus, we all know that karma (in the many forms it can take) can be pretty ruthless when it wants to be. If you've been at the receiving end of bird poop a few too many times lately, you might want to rack up some karma points as soon as possible.
