Coffee and Cigarettes

Hi all stemian friends ..
I want to tell you about the habits of people and including me as well as gathering with friends. And these habits we often encounter in everyday life.
Why at every table in the coffee shops, a cup of coffee is always accompanied by a pack of cigarettes?
What makes coffee and cigarettes a difficult couple to separate?
That is a question I myself can not answer. Ha ha
But in fact, many coffee drinkers who smoke and smokers certainly love coffee. This will be a very difficult habit to get rid of. Because coffee and cigarettes have become a partner and we can not separate.
