what about making sure your work looks decent?
i had a water main replaced because it was leaking
this employed 2 companies, a plumber and a asphalt company
the plumbers left a Styrofoam coffee cup and a macdonalds cup laying in my yard
before they could get started, they had to cut out a section of the sidewalk and they ran some yellow tape around the "hole"
when the asphalt guys filled the hole, they cut the tape so they could fill the hole and left it there
neither one of these companies will be getting my business again, because they couldnt take 37 seconds to clean up after themselves
