Query: switch broke after 9 months

I arrived home today from work to find the Mr Coffee warmer still on and heating. I assumed I must have forgotten to switch it off though I try to be careful about that but I had turned it off. Should I feel lucky it didn't start a fire? It didn't even last a year so easily rates as a piece-o-junk in my book.
