Some people like to solve problems that don't exist and then try to convince the rest of us that the problem did exist so we can pat them on the back. Generally the only time the fridge would need to be open longer than a minute is if you're cleaning it or adding new groceries and rearranging things, but in those situations it's trivial to press the alarm off button.

Right? I was raised that way. My girlfriend clearly wasn't. I always close the door in between grabbing/fetching more stuff to put inside. It takes a couple of seconds I guess, but keeping it open for a long time is just really wasteful.

Groceries and cleaning come to mind. To be honest it is a very minor inconvenience but I have been looking for an excuse to get my hands dirty with reverse engineering a circuit. The problem was just annoying enough to act as a motivator.
