McDonald’s Parkrand-pathetic service

Lastnight we ordered at McDonald’s Parkrand and the food was pathetic. The burger patty was so dry, they didn’t even put gerkins which gives the McDonald’s Big Mac it’s signature taste. The lady that took our order was also very stubborn and not helpful at all. We had asked her to upsize the meal then she charged us for a large. She was too lazy to put in the code to upsize. We then asked for normal regular meals. This is the closest McDonald’s to us and we are going there on a regular basis and the service and food goes from bad to worse. The previous time we ordered they only put 1 patty in a Big Mac ? How does that work ?
