As time goes by we all know that it takes less time to do the same job. We are now familliar and have a cleaning routine. I always try to see how fast/efficient I can be and still get the job done right. Friday morning on our last job of our "workday", a car dealership, I had finished all but hard floors in the service area and rest rooms. I always dustmop then use the extension hose with crevice tool on my vacuum to get under the vending machines and along/on top of baseboards. I saw a dead roach behind a vending machine and in my rush to get the job done forgot that the employee time clock was mounted on the wall where I was bending/reaching. I hit my head on it so hard I saw stars! Certianly slowed me down, I'll tell you that! So much for productivity! I still have a goose egg on my head to remind me. So, the moral of this story is that productivity & efficiency are important, but not to the point of distraction!
