I work near this Jamba Juice so I've come here a few times for a smoothie. The first time I went in there I wasn't greeted and had to get the cashiers attention as she stood in front of the register on her phone.
The second time I went in I ordered my smoothie and when they handed it to me, it was even filled to the top. If I'm going to be spending $7 on a smoothie it shouldn't be over an inch under-filled.
The third and final time I went to the Jamba Juice, there was a hair in my smoothie :)
