Fresco y rápido

I have been going to the restaurant for some time now and this visit will be my last. Out of convenience I would go here but after today's encounter I can no longer put up with the lack of customer service. I was the only one in the store along with two female employees. I ordered my breakfast and the employee began to pack and bag it I told her that I would also like to order a smoothie and she proceeded to raise her hand as a gesture to wait and she walked away from me and to the bathroom! I was in shock how to do you leave a customer at the counter and just walk away without excusing yourself or letting your coworker know so she can continue with the service. Once I waited two minutes I proceeded to get the other lady's attention and she began to prepare the smoothie. Upon check out I was charged $14 for a smoothie, 2 bananas, and a breakfast order of 2 two green bananas and one fried egg. I asked the lady why is the smoothie so expensive $7 and she stated its because I wanted it with orange juice instead of milk. I completely agree with other reviewers the prices always change because yesterday I ordered the same exact smoothie and it was $5.
