This location was clean and very friendly so I need to clarify on the reason for such a bad rating. I tried a new molten hot chocolate, the girl behind the counter put a sticker on my mug to determine which was my drink. My recommendation is to ask the customer if it's OK to do this before you do this. I noticed the barista cleaning my mug with hot water and wiping my mug down and she couldn't get the glue off my mug. I have now washed my mug several times with soap and water and the gooey stuff has not come off but now smeared across my favorite mug. Perhaps this is some process improvement that Starbucks can make or change the type of label that is used.
