Large companies keep records of former or prospective customers, assigning to them ratings that reflect how difficult a customer might be.
Many people think it’s creepy but I’ve had a positive experience with this rating system. When a chirpy gentleman called me from Charter to recruit me as a customer and had the gall to INTERRUPT me, I flew into a fit of rage and hissed at him in scary ways. (I never get interrupted and am not about to start).
Since then, I only get phone calls from Charter that feature very quiet, extremely obsequious telemarketers who never interrupt.
