OP here. So just to give some more information.. I open bags of chips upside down on purpose because I know it bothers people, ( it bothers my ocd too but it's funny ). The guy that slapped my chips down was actually a friend of a friend that I didnt recognize. My friend was inside laughing his ass off.. From the looks on peoples faces, they were horrified which is what made it even funnier. Btw yes I got some new chips ( which I also opened upside down ) and we even cleaned up our mess. For those of you wondering - flaming hot cheetos.
