The best restaurants serving Fast food food in Chestfield and Swalecliffe Canterbury South East

The app failed so couldn't pay. Went up to counter waited approximately 1 min to be served. The lady informed me that the app is not working and was told I could tell her my order or use the self-service machine.i said ok I will do it here with you. She said ok have a nice day and walked away. I was confused as to why she did that. So we used a self-service. After I orderd we waited for our food we got all but 1 meal that was replaced quickly. This mcdonalds has purpose built delivery bays but the drivers use the car park that already has limited spaces
