Besides, it's fun. My phone has been listed under my wife's uncommon maiden name forever, providing me with early-warning telemarketer radar. It's even better when the phone rings in my office, on the line that's only used for data and an occasional outbound call. I know it's an unwanted sales drone. It's great fun to hear them stammer and try to regain the upper hand.
Time is a telemarketer's only asset.
The more calls they complete per hour the more commissions they earn, so wasting their time is the most effective way to make them miserable. They usually give up after just ten minutes or so, but it's better than nothing. I got them into the act. I'd like to talk to you about it, but I'm in the middle of cooking something. Here, talk to my kid for a minute.
