Met friends of mine for dinner @ Chef Mickey's years ago, their first (and only, so far) visit, and their first night of that visit. Brother picks up napkin to do "twirl" and promptly whacks little sis in eye with "kinder hard corner/edge" of napkin, culminating in a huge crying scene. CM was so great - got a rubber glove, put chopped up ice in it, and gave it to her - made us all laugh. It def. worked. Great response from CM, and much appreciated. It didn't ruin their trip or anything, but we all still remember and talk about that incident, years later.
