At home I have a one touch so starting it isn't so bad....but I do usually find myself stopping it before the six loud beeps that tell me it's done. But like you the one we have here at work is a bit older and it screams every time you press a button.
Yes because it beeps like six times and is aggravating. The one in the kitchen will keep beeping until you open the door. I have wanted to rip the door off on occasion when I was upstairs.
I guess I'm a little edgier. I usually don't stop it until I feel like it's about to hit zero. There's a good half of a second there after it reaches 1 that I hold my breath.
It never occurred to me that there might be such powerful emotional wrangling about a beeper. I can understand being uptight about a truck backing up, but not a microwave.
