ABSTRACT
Have you ever visited one of those all-you-can-eat buffet restaurants where there seems to be an endless array of delicious-looking food just waiting for you? If you’re anything like me you may begin by having a look at what’s on offer and then fi ll your plate with the items you love or that look especially appealing. When you join your friend back at the table, you notice that they seem to have one of your favourite dishes on their plate. You ask where they got it, only to be told that it was being poured into the buffet bar right in front of you. You missed it.
