Can you help me understand the appeal of Starbucks?

So many drinks are $5 or more. Teens love it, more so than DD or other local places. Is it because of the chic atmosphere?

A friend goes every day and she gets it with a pump of this and a pump of that, and it’s like $6 a day.

I’m not cheap and I’m not particularly frugal, but I am not into paying $5 for a drink.
