I placed an order for Subway. I do this often. I don’t place large orders. I started out stopping by, placing my order and going home. They suggested that I use the app and I began to do so. I am now being charged a small order fee, service & delivery fee’; I know there is a tip and try to increase it. What are the all these extra prices? I order through my app and they use Door Dash. Why are they not paying these fees?
