A bottom-feeder of today's society, a telemarketer is tied into a computer that automatically harvests phone numbers out of electronic databases and always calls you while you are eating or having sex or other related activities. A telemarketer is the lowest and most devolved of life forms. Telemarketers are impossible to get rid of even if you contact their so-called preference service. Most telemarketers are marketing some mortgage, insurance, credit card, or charity scheme.
