In England, the reward for a bagful of blood is a cup of tea and a biscuit. But here, after being disconnected from our tubes, we were shown to a long table manned by volunteer waiters. What would we like? Coffee, chocolate, croissants, brioches, sandwiches of ham or garlic sausage, mugs of red or rosé wine? Eat up! Drink up! Replace those corpuscles! The stomach must be served!
