I think he tried to tell us this tale: He and his partner (from here on called the other guy) planned on opening a café together. As it turns out, the other guy wants only old customers (?), yet size 38R prefers new customers (?). Hence, they started arguing and in the heat of the argument, size 38R unscrewed the other guy's head ("business partner not has head screwed on"). Thusly, he's opening the café on his own and will buy the coffee machine on his own too. The café will open in August. Any member of SF will get free coffee.
