My microwave beeps five times when it's finished. If I'd known it was going to do that, I wouldn't have bought it.
Two beeps makes sense, in case you didn't hear the first one. Three is being on the safe side. Health and safety and all that, I can let that go. Four is overly-extravagant. Five is just taking the piss. I mean, who needs five beeps? Anyone stupid enough to need that many shouldn't be handling a microwave in the first place.
Five is being sarcastic. It mocks. It grates. Instead of a beep, it may as well be a high pitched, reedy-farty sound.
Don't stand for it. Let it get to three, then switch it off. That's what I do.
