Something's rather off there though - if you found a pile of business cards in the street like that (and consider it a potential security risk), why would your first thought be "oh, I'll get in touch with a social media presence" who then records the conversation? Sounds bellendish to me.The half colonel sounds like a proper knobhead. “How dare you speak to a lieutenant colonel like that?” Hahahaha, what a complete d1ck! I thought those days were long gone.
Just call the guy and politely point out that he's lost the cards.
