He had a strange hobby, borne out of his very specific circumstance. He had a mild aversion to cooking, slightly too much money, and an interest in human-machine interfaces in organizational settings. Thus armed with these preconditions, he set to work
Soon, he discovered what could only be described as a lack of consensus. An input in one location led to a different outcome than in another, and in a third, and so forth. Gradually and systematically, he tested out the parameters, documenting the variations as he went. After much ado, he had a comprehensive map of the permutations of the local area. The reasons for these seemingly random differences eluded him, but this did not perturb him overly much. If it worked, it worked, and that was sufficient
His friends, however, were less than impressed by his efforts, and more than once questioned his sanity. Nevertheless, he used his newfound knowledge to great effect. Entering in an order for extra halloumi into the machine of one franchised burger joint resulted in significantly more halloumi than at another, while the reverse might be true for fries. Removing one ingredient whilst also adding more of another similarly led to different results. And so on and so forth for the multitude of locations in his vicinity
