It seems like customer service is not important here. Every time I come to this Starbucks, I hope that it'll be better than the last time, but it's usually not.
Baristas tend to be unfriendly, and seem like they don't enjoy their jobs. I've been both greeted poorly and ignored by some baristas here.
The drive-thru is usually unnecessarily slow. By the time I get up to the window, my iced coffee hasn't even been made--even though there are other drinks sitting at the window.
Drinks are made carelessly. Many times I've gotten my drink and it's either overflowing, or there is sticky caramel sauce on the edge of the cup. I've even had a few ripped cups, which--since I didn't realize until I had driven away--resulted in coffee spilling into my cup holders.
Customer service says a lot about your business, and unfortunately, this Starbucks is lacking in that department.
