Why do people go to cafes?

I like coffee very much, and I also like cafes very much. I used to think that if you go to a cafe, you must drink coffee.

But most people are not like this. They prefer to order a glass of juice or a smoothie, order something to eat, and chat loudly with their friends in the store.

I was one of the few people in the coffee shop. I went to the shop because of the coffee.

So I want to know, since we call it a coffee shop, why do the people who go to the shop tend to be non-coffee drinkers?

What is the purpose of their going to the cafe?
