I had 2 bright 'cenzus' people at my door. Politely asked them to move outside the gate because of trespass.
Walked them out and conversation ensued.
"We have cenzus form for you to fill"
I- thank you for your offer but no, thanks'
" You'll have to fill refusal note then"
I- thank you for your offer but no, thanks
Didn't ask for NAME at all. Thanked me for my time and walked away.
