Free Coke?

I did something a few days ago I never thought of doing. I brought a person at a restaurant their meal. It was really cool because I gave the waiter my card and told him not to only pay for mine but for the guest that was eating across the room for my. The waiter initial reaction was "What?" I replied "You heard me." He didn't quite understand why I would be paying for someone's meal. After he came back the expression on his face was the same. It was one of those faces like this person is weird and why would he be spending money on someone he doesn't know. I felt good the rest of the day. I spent money on someone I didn't know and wether or not I changed his day for the better it did mine. Something as simple as giving something to a person or smiling a person that you walk by could change their day for the better. Everything could be going wrong and that smile was the one thing that went right for them that day. This gesture is one thing I may attempt to do more often
