    I came here to get a sandwich but they're stove was out of order so I bought a whoopie pie. The view getting back into my truck was spectacular if your vehicle is pointed towards the mountains!

    I understand as a manager myself when things get busy. To the woman with short dark hair, please work on your attitude. You were rude, add the RBF and you gave the vibe even you didn’t want to be there. If you don’t want to be, why would we? Also, talking smack about your customers in front of customers, really bad taste lady. You don’t belong in customer service.

    Too much ice in large ice coffee, not a lot of coffee almost filled to the top with ice.
