Subway

On Thursday June 28th, I was in the subway restaurant with my son. I was getting good him to practice ordering when it was his turn to order the man behind the counter was extremely impatient and rude. He was mocking my son because he wasn't giving him eyeecontact and because he was being indecisive. I yelled at the man behind the counter and he ignored me and continued to mock my son. I was so disgusted. What kind of customer service is this? I expect this incident to be dealt with immediately as it was a very bad experience for my 9 year old son. This is discaugsting behavior!
