I went inside because the drive thru line was long. At first glance the floors were filthy. I waited for about 30 minutes for someone to take my order there was a lady in front of me and a line behind me. The Manager finally came out to help the lady in front of me then she left. She came back up front and told the young man that was waiting to complete his order, to work the register or go home. He responded that a customer had been waiting 30 minutes and he was trying to get him his food. She continued to yell at him in front of the customers. He asked her not to yell at him which only agitated her more. She told him again to get the customers food and go home. Meanwhile neither I nor the other customers had been helped. A young man that was waiting behind me said excuse me can we get some help. Another customer said she'd been waiting on her food for 30 minutes. This was very unprofessional so I left. The customers behind me and I discussed how unprofessional she was, also the customer that the young man assisted was upset that he (Mc Donalds employee)was treated this way. I'll never go there again.
