In my initial report I uncovered an unknown habit of orientating my chicken and mushroom slices so that they were chevron down (or "robus-originalus style"). This, I wasn't sure, my have been related to some evolutionary style learning based on bad experiences leading to the subconscious orientating of this particular midday snack.
I've now been fortunate enough to witness the disastrous events that follow a chevron away (the so called "diablos-sinistirus" style) positioned eating style. They were captured on camera phone shortly after the event, so that we can now bring these results to you as firm evidence of their occurrence, and how they seductively point towards a Darwinian theory of eating practice.
The result: As a left sided bite pulled away the chicken and pastry, the force quickly dissipated in to the higher up pastry. The higher up pastry (the pastry plateau), had little or no structural integrity in that direction, so swiftly it came away towards the eater. Thankfully my mind was on the food and not my work at the time, so my quick reactions allowed for a rapid cessation of eating and averted a culinary disaster. Next time I might not be so lucky.
