Very unsatisfied with the service. Went to emerald city smoothie in east /midtown bend at 5:15. No one came to the counter.. was waiting for a little over 5 minutes finally someone came out. The customer service was terrible along with their math skills. Used a 50$Bill when my total was 8.70 and I got 1$ for change back. Very unsatisfied. You just lost a customer.
