Our last apartment had a microwave that insisted that the off/cancel button was ONLY for the microwave part and NOT the timer part, and if you tried to use it to turn off the timer, would display a message saying “push timer button to turn timer off” (or smth to that effect). I found it infuriating. I told my wife, “if they can program it to sass me, they can program it to turn the damn timer off.”
Anyway. I get it.
A miserable little pile of documentation.
