Lunch Explosion

[click to enlarge]

I came across this apparent "lunch explosion" on the sidewalk the other day. It really peaked my curiosity as to how it got there. The entire wrap/sandwich was lying on the ground, with its packaging a few feet away. Did someone throw down their lunch in a fit of disgust and rage? Perhaps a homeless person picked up the lost lunch, sifted through and ate the good parts, then non-chalantly discarded the rest.

I'm still curious. :)
