Exactly this! I hate when I have to clear someone else's time. It seems petty to worry about, but I always feel that it's discourteous of me to leave time on for someone else.Never leave time remaining on a microwave that’s crazy. If you have to take something out early, clear the timer afterwards.
Be patient, @Lancelot. Good things come to those who wait. Like warm and tasty leftovers for example. . .If you don’t take it out at 1 second when you have the chance you are a maniac.
