    Ordered from uber eats. Tell me how you get every single part of a small order wrong. Ordered a strawberry and vanilla frosted. Got two vanillas. Ordered a coffee with skim milk. Got black coffee. Ordered an apple juice for daughter. Got orange juice. Ordered a wake up wrap. The wrap was simply missing altogether. It’s actually impressive, to mess up an order this thoroughly. Of course, I can’t even get a full refund through uber eats. Come on people. Pathetic.

    Went there waited in a long line only to find out I couldn’t order from a person I had to use the kiosk at the counter. I was told we’re too busy to take your order. ***FYI not everyone want to figure out how to order on a kiosk!***

    Podrían ser algo más simpáticos, al menos por la mañana. Que antipática la mujer que atendió.
