If Burr said that with a straight face, he’s got a future in politics. Obviously, people with a Telezapper do not want to be called. Period. To produce a workaround and then say you don’t want to bother people is either delusional or bald-faced lying.
I leave the colorful expletives directed at telemarketing firms and managers to more expressive Dopers. I express deepest sympathy for those stuck in this line of work (as long as you don’t enjoy it). It is not a good job market and sometimes people have to take any job they can, but really, you’re doing [sub](aethistically speaking)[/sub] Lucifer’s work.
