Jamba Juice Citrus Crossing

To start, the juicer is almost always broken. Plus, I went in today and entered my reward info into the screen on the register while waiting for the girl to come take my order. I had a free boost on my account and was going to apply it to my order. This girl goes to the other register, told my to cancel the other screen and reenter it on the other register. When I did my free boost was gone. All she did was say ooh sorry and charged me for the boost. I know it's only 50 cents, but that's just bad customer service.
