If your cooker suddenly stops working, before calling out a cooker repairman, check to make sure you've not accidently switched it on to the timer setting (which is easily done with older cookers, especially a Hygena Turbo De Lux if you use the switch as a place to hang your oven gloves).
This could save you the pleasure of being charged (£30 in my case) for making a complete idiot out of yourself!
