Can I help you?
Yes, please. I'd like some oranges.
Do you want Florida or California oranges?
Which do you think are better?
Florida oranges are sweet but they are small. But California oranges have no seeds.
Then give me five California oranges.
Anything else?
I also want some bananas. How do you sell them?
One dollar a pound. How many do you want?
Give me four and see how much they are.
They are just one pound.
Good. How much do I owe you?
Three dollars.
Here you are.
