To pray for my ancestors - Cheng Beng

Yesterday I went to buy joss sticks and joss paper to pray for my ancestors.
The towkay asked me if I want to buy paper iphone to burn for my ancestors. I said they know how to use or not?
He said Steve Jobs already there, can teach them to use. I said ok loh.
He asked want to buy casing? I also said ok.
Next he asked me if I wanted Bluetooth? I said might as well loh.
What about charger? I said need charger meh? He said of course lah, after battery no power how? So I bought the charger also.
Then I asked for his name card. He said why you need my name card? I said I burn for my ancestors. For warranty claim, they contact you direct.
