Probably my favorite story about the guy is actually from my sister's tenure working for him, not mine.
In short, he had a practice of shouting from the back office, located to the right of the employee at the front desk, to issue instructions to said front desk employee. My sister worked for him for several years and was probably his favorite staff member of all time, and this was his practice for the whole of that stint. Once in a while he would emerge to find that she hadn't carried out one of these instructions, and on those occasions he would immediately begin screaming at and berating her.
For missing information he'd called through a wall into a room with music playing always. From a room located, again, to the right of the front desk.
My sister is very open about the fact that she is deaf in her right ear.
