Don't know about juicy but I witnessed a rejected marriage proposal. The ring was presented, there was a gasp and some quiet discussion, the woman said "no, sorry" quite loudly, stood up and immediately left the restaurant. He sat there for a while with his head in his hands, every pair of eyes in the room fixed on him, before he waved for the bill, paid it, and left. I could see him putting his coat on from where I was sitting and he looked utterly miserable, heartbroken, in tears. My girlfriend at the time, now my wife, said "If we're ever going to do that, don’t let it be a surprise ".
