The bartender asks a man sitting at the bar, “What’ll you have?”
“A scotch, please,” he answers.
The bartender hands him the drink and says “Ok, that’ll be five dollars.”
“What are you talking about,” the man asks? “I don’t owe you anything for this.”
A lawyer, sitting nearby and overhearing the conversation, 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 the guy, “Okay, you beat me for a drink. But don’t ever let me catch you in here again.”
The next day, the same guy walks into the same bar.
“What the heck are you doing in here!?” shouts the bartender. “I can’t believe you’ve got the audacity to come back!”
The guy says, “What are you talking about? I’ve never been in this place in my life!”
“I’m very sorry,” The bartender replies,, “but this is uncanny. You must have a double.”
“Thank you, the guy replies. “Make it a scotch!”
