I used to manage a restaurant in Blowing Rock, NC. Every time that my boss would come by to visit he would remark, looking down, that the baseboards were dirty. No matter how much I cleaned them, he would always find an area (sometimes behind a 200 pound piece of equipment) that needed more scrubbing. On one of his visits, as he looked down and remarked that the baseboards were still not as clean as they should be, I told him that if he would look up he would see that the ceiling tiles were spotless. This was probably not the best thing to say to my boss, but it does help illustrate a point here.
