So this bloke walks into a pub and the barman says "Good evening sir, what can I get you to drink?"
The guy replies "A pint of bitter please". The barman pours the drink and asks for £3.60.
The man refuses to pay saying "You asked me what you could get me to drink and that constitutes an offer of a free drink".
The barman angrily replies "Now don't start messing me about. £3.60 please!"
With that another guy sat at the bar says to the barman, "Look, I don't want to interfere but I am a lawyer and your wording of what can I get you to drink could in law be taken as an offer of a free drink".
So the barman says to the customer "Enjoy your free pint then but don't you ever try that on with me again".
Well, the next night, the same guy goes into the same pub with the same barman.
The barman says "I'm ready for you pal". The bloke asks ""What are you talking about?"
The guy behind the bar says "You were in here last night conning me out of a free pint".
The punter replies "I don't think so. I've never been in this pub before in my life".
The barman sighs and says "Well, you must have a double then" to which the guy answers,
"Thank you very much, I'll have a whisky!"............
