Microwaves - great machines to have, but with one annoying feature in the design.
My old Microwave had a turntable that went round in 12 seconds, so put a jug with a handle at the front, set it for a whole number of minutes and open the door to find the handle at the front. Perfect.
New Microwave and for some stupid reason it takes 13.5 seconds to go round, so put a jug in and guess where the handle will be when you need it when it's bloody boiling hot.
