The Most Expensive Model

mr. frith:I like this television very much. How much does it cost?
assistant:It's the most expensive model in the shop. It costs five hundred pounds.
mrs. frith:That's too expensive for us. We can't afford all that money.
assistant:This model's less expensive than that one. It's only three hundred pounds. But, of course, it's not as good as the expensive one.
mr. frith:I don't like this model. The other model's more expensive, but it's worth the money.
mr. frith:Can we buy it on instalments?
assistant:Of course. You can pay a deposit of thirty pounds, and then fourteen pounds a month for three years.
mr. frith:Do you like it, dear?
mrs. frith:I certainly do, but I don't like the price. You always want the best, but we can't afford it. Sometimes you think you're a millionaire!
mr. frith:Millionaires don't buy things on instalments!
