Two men working hard all day can put in a split AC/Heat system. However they have to hustle the whole time in the summer heat to get it all done.

Blanton's methodology is to send somebody else out to fix these little issues ASAP which is good I guess, but if they didn't push the installation crews quite so hard there wouldn't be as many little issues to fix.
