Induction cookers must have been designed by the same person who designed the door opening and closing mechanism on Virgin train toilets. For those who haven't experienced that particular abomination, they had sliding quadrant doors and separate buttons for locking and unlocking the doors as opening and closing the door. Originally the colour of the lights around the buttons was the only clue to the state of the lock (I think these have been redesigned). This resulted in the unintended comedy of someone sat down to do the toilet as the next person came along, pressed the door open button and slowly unveiled the person doing their business to the whole carriage of people. Inevitably resulting in a mashing of buttons from both sides trying to get the door to close again.
