Three Little Chip Bags, Sitting In A Row

I was just in the kitchen at my office and saw something very strange. On the table (where people often dump food that's meant to be shared) were three bags of original Lays potato chips. Three bags, each already opened, and each with the same amount of chips left in them (just enough to fill the bottom bubble). All three, folded together so their creases met up and their exact sameness was apparent.

Why would someone open up not one -- but two new bags of chips, when you already have chips available? My hypothesis: someone in this office has a phobia of the bottom half of the contents of a bag of chips and therefore can't eat anything past the midway point. But, this same person has a waste not, want not way of going about things, so rather than toss out the unwanted lower halves, he or she has proffered them up to the office collective.

Or something.

Maybe I'll think of something to write about soon that doesn't involve eating at work.
