The bartender asks Tommy who's just sat at the bar, "What'll you have?"

  Tommy answers, "A scotch, please."

The bartender hands him the drink, and says, "That'll be three pounds," to which Tommy replies, "What are you talking about? I don't owe you anything for this."

CD, a lawyer, sitting nearby and overhearing the conversation, then says to the bartender, "You know, he's got you there. In the original offer, which constitutes a binding contract upon acceptance, there was no stipulation of remuneration."

The bartender was not impressed, but says to Tommy, "Okay, you beat me for a drink. But don't ever let me catch you in here again."

The next day, Tommy walks into the same bar. The bartender says, "What the heck are you doing in here? I can't believe you've got the audacity to come back!"

Tommy says, "What are you talking about? I've never been in this place in my life!"

The bartender replies, "I'm very sorry, but this is uncanny. You must have a double."

To which Tommy replies, "Thank you very much. Make it a scotch."

Just to make it qute clear to anyone who thinks there's a personal dispute going on, there isn't.
