A man is driving down a country lane and wants to smoke a cigarette but doesn't have a light.
He sees a small pub and decides to go in and buy some matches.
Upon entering, the barman greets him with, "Hi. What can I get you?"
"That's very kind," replies the man. "I'll have a pint of cider."
The barman pours the cider and says, "That'll be £2.49."
"What?" asks the man. "I only came in to buy a box of matches, you offered to get me a drink."
The barman, accepting the ambiguity of his greeting, says, "Well, I guess I walked into that one. You can have that pint for nothing but don't ever come in here again."
The man agrees, finishes the pint, and leaves.
A few years later, he is driving down the same country lane and decides to stop in the pub and buy a drink.
He walks in and says to the barman, "I'll have a pint of cider, please."
"I don't think so," replies the barman. "The last time you were in here you swindled a free drink out of me and it won't happen again."
The man looks perplexed and answers, "I'm afraid I have no idea what you're talking about. This is the first time I've ever visited this pub."
"Really?" asks the barman. "Oh, in that case you must have a double."
"Thanks," replies the man. "Make it a whisky."
