<human>: I'll start.

I was going to the midnight release of the Nintendo DSi at Gamestop when it came out a few years ago. I'm really not too sure why my friend felt compelled to go, but I figured I would join him. There was four or five of us going. We got there a bit early and stopped at a supermarket to pick up some snacks. A friend bought a cheap 2 liter of grape soda to drink as we waited. 

Fast forward to us being in the Gamestop at midnight. I set my sweatshirt in the corner because it was much warmer inside. My friend had bought some sidewalk chalk along with his 2 liter of soda (I have no clue why). He put both of them down on top of my sweatshirt. We go about with the proceedings of the night and the original friend buys a DSi. Eventually we notice that the grape soda has gone missing. The room is very small so it doesn't take us long to scan around see where it went. 

At this point we realize that a tall black guy had stolen and was drinking our grape soda. We go up and confront him about it and he just apologized profusely. Apparently he saw the things sitting in the corner and thought it was the lost and found. He figured that no one would mind if he took the bottle. He didn't take the sweatshirt or the chalk, just the half full bottle of grape soda. It was definitely the most interesting time I've had at a midnight release.

Can you summarize the given text in a few sentences?
