America's Best Contacts & Eyeglasses review: Customer service St. Louis

I arrived at 10:35am to American best to what seemed like a warm reception.
While looking at glasses, the person told me twice that she was waiting on me. So I stop searching for glasses that were pleasing to me and accepted what was available. I stood and waited as she was already with another customer. I gave the glasses and said I will step outside for a few minutes to get some air. She said that she will get me in as soon as I returned.
I waited until the last person left and immediately went inside. She looked at me and then went in the back. Not sure about what or why, I waited.
She returned and told a gentleman to have a seat. I asked her how long would it be, because I have medical ride that have to pick me up and I wanted to let them know. Her attitude was very scolding, saying: " You were Early on your appointment!" "I was trying to help you!" I said, you told me when I come back inside, that you will take me next. And I've returned and you have told me that you will take me. She get irritate and said , she waited on me and kept reminding me that she was waiting to check me in. And tried to explain that, I was be patient because you had someone at your desk! And I was waiting until you called me. Her response was know you have to wait! I disregard her attitude and asked if there is a problem. Maybe I can speak with the office manager. She snapped, " I am the office manager!" I disregarded the nasty tone and belligerent comments. At that point, I've decided to speak with corporate about the problem.
