Coffee 15 minutes, Why not!

In Vietnam, coffee store is popular and everyone often have some cups of coffee in the morning or in the evening. They can lose many hours at these places, and it seems to be not suitable for business man. Actually, their works may be discussed here. In my experiment, our creation usually happens within fifteen to thirty minutes, after that we cannot have more anything new or good. So, that's why I'm thinking about coffee 15'. Using coffee and environment around us, the interesting feeling will help us to make creation.
Coffee 15' does not mean we drink coffee in 15 minutes. It's just a method to have fun in that time. And it's great if the coffee stores understand their customers' feeling.
