I have had a similar two-part conversation (Glock version) with a persistent magazine salesman. Haven't had a magazine salesman at the door since.
My Dad and Mom had someone banging on their door a couple weeks ago at 7:45am. Dad looked out the window and some strange guy was cranking his neck to try and see through another window from the porch. Dad always answers the door with a pistol and walked over to the front door and proceeded to chamber a round into his Glock 19 and the guy starts hollering I am just taking a survey! I’m just taking a survey!
Dad opens the door with the pistol behind his back and the guy is back off the porch nearly in the yard babbling I’m just doing a survey for XYZ. Dad says not interested go away and slams the door and locks it and the guy takes off down the yard to the next house. Survey guy hasn’t been back.
I personally dealt with census goober in 2000. I had sent my form in answering how many lived in the household and left it at that. Some censusette shows up while I am cutting grass and identifies herself as a census taker here for a follow up since I hadn’t answered every question. I said you have all you are getting out of me. But you have to answer! I don’t have to do anything dear I replied. I commenced to start my tractor up and she says I will just ask your neighbors then to which I replied knock yourself out lady as I fired up the tractor and drove off.
In 2010 my wife got the census person and she got an even more sharp response from the Mrs. and left forthwith with don’t waste my time anymore ringing in her ears. Of course this same lovely Lady who is my bride came within a half of foot of drowning two Jehovah Witness who also ignored our No Trespassing sign, they haven’t been back in 13 yrs.
