There is a cafe located in France which looks like ordinary, and actually this café has a booming business. Today, one way valve tells everyone that the reason why this café has such booming business. Now let us together to see.
When a chubby man just have a seat and embraced with the lady of next table, then order a cup of coffee and sit down, and I saw waiter only charged 1.4 euros from this man.
I went to the service desk to order coffee and said to the waiter in broken French, "I want a cup of coffee." The waiter slightly surprised asks, "Could you repeat what you said, okay?" Then I timidly repeated it again, "I want a cup of coffee." The waiter gave me a cup of coffee and told me: "This cup of coffee is 7 euros, lady." Then I asked again, after confirming that it was still 7 euros, I had no choice but to pay.
After taking away the coffee and I complain with my friend,” what’s happening? Why I order the same coffee, the waiter charged 1.4 euros from the man, but charged 7 euros from me? That’s unfair!”
After a while, there is a grace lady come to the service desk and said to the waiter, “Please give me a cup of coffee, okay?” Then the waiter gave her a cup of coffee and charged 4.25 euros from her. At this moment, I found the same cup of coffee has three prices, and they are 1.4 euro, 4.25 euros, and 7 euros. My friend said, “Did you pay attention that what is waiter said? If you said, “give me a cup of coffee!” The price is 7 euros; if you said, “Please give me a cup of coffee.” The price is 4.25 euros. But if you said, “Hello, could you give me a cup of coffee, okay?” Even give an embrace with a stranger, the coffee price is 1.4 euros.”
It's a good idea that with different price of coffee to remind people of courtesy. In this particular way to told that people should treat each other with courtesy and get along with people in an elegant manner. A cup of "polite coffee" not only brings us a warm and comfortable atmosphere, but also cleverly allows everyone to experience the "polite" pleasure.
