Why is it that you can't buy yellow bananas anymore? I remember being able to go into a supermarket and buy yellow ones but now they're all green.

"But they'll ripen at home sir".

So what am I supposed to do in the meantime if I want a ripe banana? Invent a time machine so I can go forward to that exact moment when it's ready to eat? But I couldn't just buy a ready-built time machine, could I? It'll come as a flat pack, and I'll be all excited about building it and the ultimate reward of a yellow banana but it'll take me two days to build it because the instructions are in Chinese and make no sense. There'll be 2 screws missing and a bolt that isn't even in the instructions. By which time the banana will be ready to eat anyway and I'll be in a faulty time machine on a one way trip to the land of the dinosaurs.

How long before the tomatoes are sold green "so they can ripen at home, sir"? If it's about making it easier for the supermarket, they might as well just sell us the seeds and we'll grow them ourselves.
