At my old job, an older guy worked for me. He was just generally loud/obnoxous/kind of gross...anyway, he has a son that was horrible; 30 ish, loser. They would get in screaming matches over the phone frequently during work, much of the office could hear. So, I tried to be polite, and sent him an email during one particularly long call asking him if he could maybe take calls like that on his personal phone outside or in the breakroom. I thought he got the hint, however, shortly after hanging up with his son, and he'd gotten my message and I think even replied, saying he was sorry and that "David is just a dumbass" he calls up his wife and lets her know that he just got in trouble for yelling at their son during work. He is generally a loud speaker, so everyone also heard that...
