The bartender asked a guy sitting at the bar

The bartender asked a guy sitting at the bar: “What’ll you have?”

The guy answered: “A scotch, please.”

The bartender handed him the drink and said: “That’ll be $5.”

The guy said: “What are you talking about? I don’t owe you anything for this.”

A lawyer, sitting nearby and overhearing the conversation, said 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 understandably unhappy, but said to the guy: “Okay, I’ll let you off this time, but don’t ever let me catch you in here again.”
