The dumb 'pretend' game

Two simple minded men are trying to amuse themselves because they are bored.
One says to the other... "Oh ! I know. Let's play a game of 'Pretend' !"
The other one not knowing what was the game asked what he had to do...
"Simple !" said the other. "I will 'pretend' to be a Butcher in a shop and you come in as a 'pretend' customer and 'pretend' to buy something.
The guy playing the customer part says "Ok, lets do this !"
He turns around while the Butcher 'pretends' to be working.
The customer compose himself, turn around and 'pretend' to enter the Butcher shop, and says "My good Sir, would you be so kind as to sell me 3 bottles of Coca Cola, please ?"
The butcher, not pleased, explain to him that he has it all wrong. That a Butcher shop sells meats and meat products only.
So the customer 'pretend' to go out and after a short while he 'pretends' to comes back in and this time he says "Hello again my Dear store owner. Would you, by any chance, have any bottles of Pepsi please ?
Now the butcher is really mad and tell him to come back when he knows what he want.
The customer went away wandering what was wrong. But even if he was a simple minded man he realized what he was doing wrong. So he goes back and this time he says "Good Morning to you good man ! I would like to purchase 1 whole chicken, 2 steaks and 4 sausage links !"
The butcher, grinning with all his teeth is in a really good mood and chat the customer about the temperature and other stuff while 'pretending' to make the customer order. After a few minutes, he steers the customer to the cash.
The customer asks "How much will it comes to for my order ?"
The butcher replies "It comes to $17.54. Where are your empty bottles !"
