olive oil and fizzy pop

While purchasing groceries yesterday, there was an older gentleman standing in line behind me. He had grey hair, a grey moustache that curved up at the ends and a combination of grocery cart items that intrigued me. His purchase consisted of approximately half a dozen 2 litre bottles of pop (something like sprite with lemon flavour) and approximately half a dozen 750 mL to 1 L bottles of extra-virgin olive oil. Nothing more, nothing less. I couldn’t help but wonder: what was the story that went along with that? Your thoughts?
