Likely zero. "boulos" was probably tapping away at something on his phone or listening to headphones and didn't respond when the employee at the deli counter yelled "Next." Or maybe, it was as simple as an 80-something year-old guy not feeling comfortable leaving his 80-something year-old wife at home alone for long.
Whatever happened, boulous is still so bitter about it that he felt it necessary to post this story on the day the man died. Says a lot more about him than about John Madden.
