If you don't like your Starbucks order for any reason, you can bring it back to the store and ask for a remake or a refund. Starbucks has a policy of making things right for customers and ensuring that they are satisfied with their experience, so if your drink doesn't meet your expectations or there was an error in preparation, the barista will be happy to make you a new one or provide a refund. It's always best to let the barista know right away if you are unhappy with your order so that they can address the issue and make things right for you.
