Worst service ever at Bruma McDonald's

Mcdonalds Bruma doesnt even deserve 1 star. Went to order at the drive through and ask for chilli cheese fries and get told they dnt have. Fine place my order get to the window and pay. Now I wait for my order. Took a while so the lady in the car behind us gets out and comes to the pick up window and says please can I get my order quickly i have an emergency and its just chilli cheese fries. Wow I thought they never had. How can they sell to someone else and not me. I will not support them again and the quality of the food has gone down.
