Security give you grief for parking outside the entrance when its raining

The security give you hassles about parking outside the entrance to collect your food when its raining. If I was shopping somewhere else in the centre and not at McDonalds then fine, give me grief BUT WE WERE BUYING FOOD AT MACDONALDS! If this is the way they want to treat customers then I will never be returning ever again. Treating PAYING customers like this is TOTALLY UNACCEPTABLE!
