I don't understand people who put food in the microwave (at work) and then go back to their desks to work for a bit. It takes all of 3 minutes. Plus, you're just making it awkward for the rest of us...I mean, if you're not there and the timer has gone off, is it okay for me to remove your food? What if it's obvious that your lean cuisine isn't completely heated? And, what's the grace period for waiting? Do I wait 3 minutes? 5? Indefinitely until you return to claim your food? I just don't know...which is why I tend to bring peanut butter sandwiches for lunch.
