The Perils of Fine Dining

 So, apart from the handful of courtesy phrases I remembered from the time a few years ago I studied a bit of Greek, I remembered or picked up a number of mission-critical words: krasi (wine), aspro (white wine), krasi kokkono (red wine), byra (beer) - I'm sure there were others, though I don't remember them right now.  But there was also "estiatorio," for restaurant.  One restaurant had a very neat design (see second photo): a set of thin stainless steel shapes nailed into the wall, meant so that each one resembled a fish (with the nail being the eye) but that the whole group looked like a school of fish, swimming toward the restaurant so that we could eat them.  OK, so fish aren't smart, especially ones made of steel.  Turns out that there was a similar work of art inside the restaurant, right behind our table, right about upper torso level.  And it turns out that there's a mathematically good probability that someone in our party might rise abruptly from her chair, wheel around to leave, and stab herself with about fifteen very narrow, very sharp, stainless steel fish-shaped stakes.
