I recently visited my friend on the base and I had run out of essentials. When I arrived at the store the sales clerk was talking on her cell phone and ignored me. When I asked the girl for help she told me to hang on a minute that she was busy. The girl appearred to be fighting with a boyfriend or husband and I heard the entire conversation. I tried to ask again for help and she turned her back to me. I then asked her for the manager and she said she was the manager. Service was horrible at the GNC store on the base in Sierra Vista.
