Starbucks at 264 Redwood Shores Parkway, Redwood City, California.

Ordered two drinks, one in which my mother said it wasn't the drink she had ordered and I still hadn't gotten mine so I went up to ask for my drink and asked if they can give me the drink my mother ordered.
Well they did give me my drink but two of the women were talking to each other discussing that it was the drink, acting like uneducated little girls whining about them being right.
First of all, I never said she was wrong but my mother did say it didn't taste the same as what she usually gets so all they could do is just listen to the customer and change it rather than talking back and whinning about them being right.

Super friendly staff and very accommodating to people with questions.
