@jdb7566. Leaving trash behind is common among all construction trades. I was an assistant superintendent for a builder. That was my pet peeve, I made all trades clean up their mess, If i caught them urinating in a unit (more common than anyone wants to know) I terminated them no questions asked. Even in my own house I found beer cans stuffed in the bathtub frame when I had to replace the whirlpool motor. I get that those things happen, shouldn’t, but they do. I can excuse messyness that doesn’t compromise quality, but I cannot excuse poor workmanship.
