"If you want someone to put meat in your bowl it's better to stand to the side so they can get to the bowl rather than right in front of the bowl (in the way) facing and criticizing the person who is kindly trying to fill it with delicious meats.
For example, when I go to a restaurant I don't stand in the door to the kitchen yelling at the waiters as they try to bring out the food. Because I would be "in the way" and then it would take longer to get the food. I also don't try to trip them."
