ok my last attempt at this spiraled out of control...take 2. Our center was improving over some time, but we were always finding air in the catch cages and elsewhere when we walked our belts. Our f/t supe would always ask us if we walked our belts, checked the catch cages before the drivers left. We would always say yes. A few times after the building was pretty much empty I would take empty NDA letters and put them in the catch cages. I would wait til I saw our f/t in the area then pretend to find about 8 NDA letters. The reaction was always priceless.
