I hate sales calls that I didn't ask for, and won't deal with any business that does them. I don't give my zip code, etc to checkout persons in stores, either. Since when do you have a RIGHT to datamine me ceaselessly? LEAVE ME ALONE.
My husband likes to screw with sales calls. We have onscreen caller ID, so he can tell. If it's a man, and they ask for me, he'll go all crazy on them "WHY ARE YOU CALLING MY WIFE, huh? Are you sleeping with her??!!" He does accents. He goes all freaky and starts talking about how the phone is bugged by aliens and does Franco have the shipment ready. He answers as Such-and-Such Correctional Facility and informs them that the person they are trying to reach is an inmate, and tries to get their name and number and asks all kinds of belligerent questions on how they know this person, why they are calling this prisoner, treating them as a suspicious character. I prefer to just ignore and not pick up, but he likes to pick up and mess with them. He's a loon. A loveable loon, but a loon.
