WHAM!
Yup, had it happen a few times. I hated it, but understood why it happened.
It wore me down sometimes, if you had a couple of them in a row. Real filthy-mouthed asinine people. The worst: this one guy who followed us down the road, spouting off putrid remarks and hounding us even at other doors. He wouldn't let up. But when we were at another door, the householder looked out and said to this guy: "DO YOU MIND? I am quite capable of handling these people, now shut-up!" I kid you not. The householder did not like this neighbour (gee I wonder why?) They were nice, told us not to worry about 'him'. They weren't interested, but were polite and friendly.
We didn't do any more calls after that. That knocked the wind out of my sales.
I could go on about others, but there was nothing particularly unique about them, just angry and obnoxious.
Glad I don't do that anymore .
