airplane interiors are quite small so like caravans everything is designed to be space efficient. this is most obvious in the toilets where everything has a function to assist you in your functions.

even i was shocked by the size of this teeny weeny metal baby changing table. it was only about 3 centimetres long and 1 centimetre wide. they tried to confuse us by putting an even smaller sign next to it, but i'm not stupid.
