I read this article online and just had to share it with you all. I am not the original author.
One day, I sat with a friend in a famous cafe in Los Angeles, sipping coffee. A man came in and sat at the table next to us.
He called the waiter and said, “Two coffees; one is for the wall.” His way of ordering coffee was so novel that we could not help but pay attention. We soon noticed that he was served only one cup of coffee, although he paid for two. As soon as he left, the waiter taped a piece of paper to the wall. It read: A cup of coffee.
Then two more men came in and ordered three cups of coffee, two to drink and one for the wall. They, too, paid for all three cups of coffee. The waiter dutifully pasted a piece of paper with “A cup of coffee” written on it on the wall. This was clearly a popular trend, but it surprised and puzzled us. However, as it was none of our business, we finished our coffee, paid for it, and left.
We had another chance to visit the coffee shop a few days later. While we were enjoying our coffee, a man came in. Unlike the shop’s regular customers, he was clearly a poor man. He sat down, looked at the wall, and said, “A cup of coffee on the wall.” The waiter brought him his coffee respectfully, as was usual for all patrons.
The man finished his coffee and left without paying for it. We watched in amazement as the waiter lifted a piece of paper from the wall and threw it into the trash can. The truth of what was happening finally dawned on us; the respect that the local residents had for people experiencing poverty moved us to tears.
Coffee is neither a basic social need nor a necessity for life. However, one must remember that whenever we enjoy something nice, we should all think of others who also enjoy such things but cannot afford to pay for them.
According to the coffee shop’s wonderful system, when a poor person comes in, he or she doesn’t need to humiliate him or herself by asking for a free cup of coffee. The person just needs to ask for what has already been paid for.
The cup of coffee thus paid for is called suspended coffee. You pay for it but do not need to know who will enjoy it. This is the world of love and beauty.
[Note: Coffee was bought in advance to help warm those who could not afford it. It started in Naples, Italy, and has spread all over the world.]
牆上的咖啡（来源于网络)
一日，和朋友在洛杉磯一家有名的咖啡廳閒坐，品着咖啡。這時進來一個人，坐在我們旁邊的那張桌子旁。
他叫來服務生說：「兩杯咖啡，一杯貼牆上。」他點咖啡的方式令人感到新奇，我們注意到只有一杯咖啡被端了上來，但他却付了兩杯的錢。他剛走，服務生就把一張紙貼在牆上，上面寫着：一杯咖啡。
這時，又進來兩個人，點了三杯咖啡，兩杯放在桌子上，一杯貼在牆上。他們喝了兩杯，但付了三杯的錢，然後離開了。服務生又像剛才那樣在牆上貼了張紙，上面寫着：一杯咖啡。
似乎這種方式是這裡的常規，但却令我們感到新奇和不解。不過由於事不關己，我們喝完咖啡，付了錢，就走了。
幾天後，我們又有機會去這家咖啡店。當我們正在享受咖啡時，進來一個人，此人衣着與這家咖啡店的檔次和氛圍都極不協調，一看就是個窮人。他坐下來，看着牆上，然後說：「牆上的一杯咖啡。」服務生以慣有的姿態恭敬地給他端上咖啡。
那人喝完咖啡沒結賬就走了，我們驚奇地看着這一切，只見服務生從牆上揭下一張紙，扔進了紙簍。此時，真相大白，當地居民對窮人的尊敬讓我們感動得熱淚盈眶。
咖啡既不是社會的基本需要，也不是生活的必需品，但需要指出的是，當我們享受任何美好的東西時，也許我們都應該想到别人，有些人也喜歡這樣的東西，但却無力支付。
再說說那位服務生，他在為那個窮人服務時，一直都是面帶笑容。而那位窮人，他進來時，無須降低自己的尊嚴討要一杯免費的咖啡，他只需看看牆上。
多付款的那杯咖啡叫待用咖啡，你付錢了，但並不知道誰會享用它。這就是有愛和美的世界。
【註：人們提前買了咖啡，讓付不起的人享受溫暖。這開始於意大利Naples，現已傳遍全世界】
