The syrups and huge quantities of cream in those drinks are killer.
In any good cafe or Starbucks, they'll be glad to explain in detail to you the composition of the drinks. (I do this at my cafe - if you're going to spend 5 bucks, I want you to like it.)

I feel it's like stealing because you're not paying for the 2 cups of milk you just took. Not to mention it's a pain to keep refilling it
