Tell him you need to get to work. He'll get the point.
I too am guilty as charged. I have always been patient when dealing with home owners who seem to talk/nag but i have aslo found myself doing the same when i have work done around the my home.After the fact, I realized I was doing it myself...dish guy came and I shot the ***** with him the whole time, following him around etc...
I hate people looking over my shoulder...I coulda started this thread, but I'm guilty!
Sorry, dish dude!
