McDonald's Chatterton rd continues to disappoint

I went to McDonalds two days in a row for breakfast this week. I was disappointed both times doubt ill go back. On Monday i had to wait 5 minutes for the casher to cash up and a new one to come in before i could pay for my drive through order. then i still had to wait a further 5 minutes. On Tuesday morning they had no milk for my coffee! I couldn't believe it how do you run out of milk, pathetic!
