This Starbucks is one of the better locations that I have gone to. They are always very courteous and they have never messed up on my drinks.
I understand that some people do not think that their prices are fair... Here's the thing. You aren't going to Starbucks for a cheap cup of coffee. You are going to Starbucks because you know the coffee will be of high quality, and you know that you are going to have a great experience. Starbucks does not mess up, and if they do not fully impress you, then they gladly give you free drinks to rectify the situation.
Always impressed, and always a happy customer.
