It's actually the opposite. People don't really take no for an answer anymore, and that's doubly true of anyone trying to sell you stuff, so instead of saying "no/ will not", we try to justify why we "cannot/are physically unable to" to stop the onslaught.

Like canceling cable, home internet. It's not that we're using something else, not using it at all, don't want it. It's "we're moving/going to jail for 5 years/dying Thursday and thus cannot continue using this service"

I had a door to door salesman ask if I was racist after I told him I wasn't interested, as if to try to pressure me into proving I wasn't a racist by listening to his pitch/buying into whatever he was selling. It's gotten to the point where I have a video door bell so know when I can skip it all by not answering//pretending I'm not home.
