One Word For Johnny

Johnny went to an electronic store, he asked
the storekeeper "what is the price of this TV?"

The storekeeper answered "we don't sell our
products to Johnny."
Johnny came again the next
day cutting his beard and asked  "what is
the price of this TV?"
The storekeeper replied
"we don't sell our products to Johnny".
The next day johnny came with a different face
and asked "what is the price of this TV?"

The shopkeeper replied "we don't sell our
products to Johnny."

Finally Johnny got irritated
and asked the shopkeeper "how do you
recognise me every time?"

The storekeeper
replied "because this is not a TV it is
Microwave Oven!"
