Home invasion sales tactics...
I totally agree. I love Kirbys but I hate the thought of a D2D salesperson invading my home and refusing to leave until I've signed a sales contract and thus would never allow one to cross my threshold. I seem to remember reading on here several years ago about someone who had to finally usher the salesman out the door with a .38 in his hand. A little extreme to be sure, but I understand the sentiment. Kirby may claim not to tolerate such tactics, but despite creating a certain degree of plausible deniability, they do tacitly condone it by not putting an absolute stop to it with a complete cessation of D2D sales.
Now, in all fairness, the salesman who did the in-home demo I witnessed as a child in our living room in about 1973 could not have been more polite and did take 'no' for an answer when my mom declined to purchase. But that was a different era and society was much more polite as a whole back then, at least it was where I grew up.
