We heard his order with ___17__ and noticed that he was served one cup of coffee _18_he paid for two.
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 19 three cups of coffee , two on the table and one on the wall. They had two but paid for 20 . This time also, the waiter did the same thing. It was 21 unusual for us.
After a few days, we had a chance to enter this coffee shop again. While we were enjoying our coffee, a man 22 appeared homeless entered. He looked at the wall and said, "One cup of coffee from the wall."
The waiter served a cup of coffee to this man with 23 . The man had his coffee and left without 24 . We were amazed to watch all of this as the waiter 25 a piece of paper off the wall and threw it into the bin.
Now it was no surprise for us---the matter was very 26 . The people of this town showed great respect for those people who needed help.
Just think about 27 this man wanted. He didn’t have to lose his face to ask for a(n) 28 cup of coffee. 29 asking or knowing who was giving him this cup of coffee, he only looked at the wall, placed an order, 30 his coffee and left.
It’s a truly beautiful thing---probably the most beautiful wall anywhere in the world.
