hahaha
all these stories are really interesting and I enjoyed them all
a similar incident happened with us a few years back, a man knocked at our door (yes he was so audacious to carry out a scam in broad day light)
and when I opened, he asked me to call an elder.
I asked my mom to deal with him, he started his rant.
"two years ago you participated in a survey conducted in this area, your husband's name is this... and you have won a 5 marla plot in (a town which I had never heard of and dont remember)."
All this time my mom kept her cool and silently listened to him, he further said, "to avail this plot you have to submit a mandatory fee of Rs 500", and then he gave us an address verbally.
After listening to all this, my mom replied, "meray bhai tum 500 rupay jama karwa kay mera plot khud rakh lo." 
his face was worth-looking at that time, and after that he silently walked away...
