Habit: Some individuals may have developed a habit of waiting for the microwave to finish its countdown over time. It becomes a routine, and they may not see any inconvenience in waiting for a few extra seconds.
Accuracy: Waiting for the microwave to complete the countdown ensures the food is heated for the exact amount of time specified. Stopping it at 1 second could lead to slight variations in cooking time, which may matter to some people, especially when precision is required in cooking or reheating.
Safety Concerns: Some individuals may believe that stopping the microwave at 1 second could lead to residual microwaves lingering inside, potentially affecting the next use or even posing a safety risk.
Perceived Efficiency: For certain people, the time it takes to stop the microwave at 1 second might not be significantly different from waiting for it to complete the countdown. In their view, it might be more efficient to wait and save themselves the hassle of repeatedly starting and stopping the microwave.
Simply Unaware: Some individuals may not be aware that they can stop the microwave at any time and assume they have to wait for the beep.
Of course, microwave usage habits can vary widely from person to person, and these are just a few possible reasons. Ultimately, it's a matter of personal preference and convenience, and there's no right or wrong way to use a microwave as long as it's done safely and following the manufacturer's guidelines.
