My sodding washing machine does this after completing a washing programme and there's no way to disable it. Seriously, does the manufacturer think I'm going to completely forget I needed clean clothes and bedding for the week?

I also notice my new microwave sits there and keeps chirping at me after heating food until I open the door, it's not as loud and as insistent as the washing machine, but still totally unnecessary behaviour.

A more sensitive soul could eventually be driven bonkers if every flippin' thing in your house and car beeped and booped at you every minute of the day.
