Just yesterday said relative bought a new toaster. I am told by the other relative he lives with, that had he read the manual, he'd have realized that you were meant to put the toaster through its paces by twice running it through with no bread in, and on its third run, setting it to setting 4/9 using a slice of moist, fresh bread. Of course this relative likes well-fired toast, so, ignoring all instruction, stuck an old, dry slice of bread in on its first run and set it to 9/9. Worse still he went for a walk round the house, rather than keeping an eye on it.
After the toast caught fire, shot up high enough to set the pine kitchen cupboard on fire, and fall back on top of the plastic-coated toaster, melting it in the process, he had the cheek to return the 'faulty toaster' to Argos demanding a refund and compensation for his kitchen cupboards! ;-)
