Why??????

Why do people whom we have hired to do work on our home always have to poop in our bathrooms. Now I know that everyone poops. BUT this always happens in our house. Today the second air conditioning guy had to use the bathroom. The only diffenrence between this one and the other one is that this one asked to use the bathroom the other one just went in and did his business without even asking. And then did not spray or turn on the fan. Of course he did not get a call back from me. Now today the next A/C guy comes and does the same thing in the bathroom. He does not turn on the fan or spray either, but he does close the door behind him. Why do men not try to cover up the foul order they leave behind. Is the work we hire people to do really that bad that it gives them the shits? And I thought all men had poop control that they can wait until they get home.
