The person complaining or protesting the loudest or most frequently is the one who will receive the most attention from others. My sister makes a point of writing letters of complaint to businesses whenever she has an issue with their service, and nine times out of ten, she's rewarded with some kind of discount or gift. I guess it's true—the squeaking wheel gets the oil. I try to support all my departments and employees equally, but the squeaking wheels always end up getting the oil.
