You'll find those are the unwritten rules that apply to every customer service dept everywhere.
Its true, Ive run several ISP's in my time and also acted as level 3 tech support.
Remember back when everyone was on dialup and you could only stay connected if enough lines were free ? Thats when I got started.
Anyway, if you rang up one of my level 1s or me and was extremely rude (ie yelling and swearing about disconnections) over the phone Id quietly add you to my "shitlist". My shitlist was part of my home made auto disconnection script, it would always ensure your account was booted at the earliest possibility when the modem banks were full and if you were a real shit you went to the 2nd shit list in which Id trigger the cisco to randomly hang up your modem and log false line errors for your connection
I can just picture Josh doing a "pressed ham" on every bitchy customers invoice slip, be warned.
