McDonald's

Tired of being pulled forward while dealing with low sugar issues. Tried to call and talk to general manager about latest incident. He said that's the policy to keep their lines moving so it does not wrap around. There was not that many cars in the drive, was pulled forward to keep their drive thru time down. When I had ordered a sandwich which would be the quickest to make a double cheeseburger... Once they made me pull forward it was brought out within 20 sec.?? I could have just got my food at the window. No consideration to the customer. (Blood sugar was 50). If it gets to 40 it can cause seizures and coma's. I will not be back after not getting anywhere with the general manager. Was not trying to get refund or food. Just trying to give customer feedback to him but got no where.
