I have recently worked in a home appliance store. Yesterday comes an uncle with a multivarka under the mouse, then the dialogue:

Q: Girl, I bought a multiwark in your store a month ago, it is boiling, but it turned out that the postponed start function cannot be used!
I am: O'Key, I understand. Two weeks have passed, the equipment is visible that we have used it, we can not return it, we can send it for a guarantee repair. * I get the documents for the SC* Please describe the defect in detail.
Q: Yes, you understand, my wife and my child left here to rest, I did not use her, well, a multi-car, myself before. In the evening I put the cabbage on a postponed start, in the morning so that it was fresh. I open in the morning - and there the cockroaches swim! Okay, I think maybe I did something wrong. I arranged dinner so that at the time of coming from work there was, I come, I open, the cockroaches again! impossible to use.

...this is how I learned that "impossible" is not the same "not working"
