Or, at least that was the case with Rio Station Juice Bar. I asked if I could order a juice, assuming that maybe the menu excluded juice simply because there would be no need to inform people that there was juice available at a juice bar. The obviously disoriented cashier said something along the line of "yes, um, juice, um, smoothie, um, juice, um, banana hammock," or something like that. So, I asked for a grande watermelon and strawberry juice and reiterated that I did not want a smoothie.
Only 15 minutes later, after battling a fly and doing the samba with the other five people in line at this treasure, I was the proud owner of a watermelon and strawberry smoothie! Just in case you were thinking of spending your day in a gigantic mall, just to defraud Rio Station Juice Bar out of a smoothie that you didn't pay for...don't even think about it! As I quickly learned, every employee will individually review your receipt for authenticity before the reluctant blender-technician hands you the smoothie you kind of ordered, but really didn't.
The smoothie was delicious, by the way. But, a juice bar should have juice. I'll never go back.
