Business

A certain man was hungry, and did not own so much as a date-speck; so he entered a restaurant and asked for a little bread and cheese. The cashier asked him:

"Do you want anything else?"

— "Yes, I would like to exchange the cheese for a tin of sardines."

— "Very well. And what else?"

— "I prefer to take a tin of meat instead of the sardines."

— "As you wish."

— "And now I must be going."

— "But you have not paid for the tin of meat."

— "Did I not exchange it for the tin of sardines?"

— "But you did not pay for the sardines either."

— "I exchanged them for the cheese."

— "And you have not settled with me for the cheese either."

— "But you still have it... good day to you!"
