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 pasted 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 again had a chance to go to this coffee shop. While we were enjoying our coffee, a man poorly dressed 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. 
 
We were amazed to watch all this when the waiter took off a piece of paper from the wall and threw it in the dust bin. Now it was no surprise for us – the matter was very clear. The great respect for the needy shown by the inhabitants of this town welled up our eyes in tears. 
Ponder upon the need of what this man want…He enters the coffee shop without having to lower his self-esteem…he has no need to ask for a free cup of coffee…without asking or knowing about the one who is giving this cup of coffee to him…he only looked at the wall, placed an order for himself, enjoyed his coffee and left.
 
Wall probably the most beautiful mural you may ever seen anywhere….!!!”
