Someone at work does this and doesn't clear the remaining time. Pisses me off. Press the stop button for the love all that is holy. Look, I know it's petty.
Not petty, totally fair. In my case, the microwave is the most visible clock from the couch, so I am always annoyed when it's 00:02 instead of the time. But then again, the power goes out frequently where I live, so it's not so reliable as a clock in the first place
