McDonalds manager unprofessional and bad service

Earlier this week me and a friend visited McDonalds Atterbury Value Mart in Faerie Glen. We waited for more than 30 minutes after ordering our food. We also requested to eat in but they gave our food to us in take away bags. When I told the cashier waiting 30 minutes for one's food at a fast food restaurant is not acceptable she called the Manager. When I told the Manager the same thing, she just turned her back on me and walked away. That is very unprofessional. The place was also very dirty with bags and cups still on many of the tables. Only one till seemed to be working and people were standing every where waiting for their food.
