    Stood there for 15 minutes while they ignored me, little spanish looking girl genuinely was so rude. My drink wasn’t filled to the top. I’m so pissed.

    The workers are so awkward and don’t talk to you at all In the drive-through lol It feels like you’re doing some sort of drug deal with the lack of interaction 😭 The least they could do is say hi how are you or have a nice day
