When he left, the waiter put a piece of paper on the wall saying “A Cup of Coffee.”
While we were still there, two other men entered and ordered three cups of coffee, two on the table and one on the wall. They had two cups of coffee but paid for three and left. This time also, the waiter did the same; he put a piece of paper on the wall saying, “A Cup of Coffee”.
It was something unique and perplexing for us. We finished our coffee, paid the bill and left.
After a few days, we had a chance to go to this coffee shop again. While we were enjoying our coffee, a poorly-dressed man entered. As he seated himself, he looked at the wall and said, “One cup of coffee from the wall.”
The waiter served coffee to this man with the customary respect and dignity. The man had his coffee and left without paying.
