I frequently go to Starbucks and I am a bing fan and the baristas are usually very pleasant and kind! Unfortunately I had a bad experience with a barista when she made me the incorrect drink. I had ordered it iced and she made it hot. It's not a big deal and I said to her "oh i am sorry, it was supposed to be iced." She glared at me and then dramatically dumped it down the drain, clearly annoyed. Then she proceeded to make it iced, and hand it to me totally unmixed and just thrown together. It was very rude and made a lasting impression on me. Customer service is VERY important I have worked in this industry before. You don't have to go out of your way to be nice, but you should definitely not go out of your way to be rude. I hate writing bad reviews but and I know everyone has bad days- maybe this was a bad day for her. But when you are working try to be professional.
