A fellow walks into a pub and has he approaches the bar the Landlord asks him what he wants to drink. "Thanks" says the fellow "I'll have a pint of best bitter"
The Landlord pours and hands over the pint and says "That will be £3.40 please"
"No" says the fellow "When I walked in you asked me what I wanted to drink and I assumed that you were buying it for me"
"Drink up and get out" says the Landlord "And don't ever come back"
Next day the fellow returns and the Landlord shouts at him "Get out, I told you never to come back"
"What you talking about" says the fellow "I have never been in this pub before, as a matter of fact I have only just arrived ion this town"
"I'm terribly sorry" says the barman "You must have a double"
Many thanks" says the fellow " make it a whisky"
