depressing lunchhours

Over the past few weeks, I have come to the conclusion that the most depressing way to spend what is jokingly called, your lunch-hour, is not eating it at your desk, which is in itself quite devoid of happiness, but in fact being tempted, due to pressure of work, to eat your lunch on the way back from the shop.
Lunch becomes a joyless, mechanical task of getting enough calories to satisfy your hunger, far removed from the ideal of a true lunch hour. Nothing like this would be recognisable in most of France, Italy or Spain, where food is valued as much as work.
