The Cup Is Half Empty Kinda Guy, Part 2

(The pub has a special offer selling pints of ale for the price of a half-pint.)

Customer: “Can I have a pint of ale, please?”

Me: “There you go. That’s £1.”

Customer: “But, your sign says that a pint costs the same as a half-pint.”

Me: “It is. A pint is usually £2.”

Customer: “That is a rip-off. A pint should cost £1 anyway.”

Me: “I assure you that a pint is usually £2.”

Customer: “Forget this. I didn’t come in here to be conned. Just get me a half-pint instead.”

(I pour half of the pint into a half-pint glass.)

Me: “Here you go, sir.”

Customer: “That’s better. How much is it?”

Me: “It’s £1.”

(The customer pays, picks up his drink, and walks off happy.)
