They advertise order ahead but it isn't order ahead if you don't even start on the order until gps confirms the customer is in the parking lot. Order ahead is for people who want to pop in and grab the food they already paid for because they need to save time. Not waiting 15 to 20 minutes on location. The order ahead feature is completely useless, and whoever designed this app that constantly glitches, freezes, and resets your McDonald's location, needs to be fired.
