Do you look at the electrical system of a building before you start? If you see that the breaker panel looks shoddy, has corrosion and multiple splices and the grounding conductor looks like it has been bent & re-bent many times and has a splice (or isn't code compliant for some other reason), recommend that an electrician inspect and repair anything needed.
Are you able to have your own circuit for the AV system?
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
