because you're too poor to afford anything else? why does anyone goto mcdonalds?
it's certainly not service that hasn't been good for a decade now. it's a consistent product not abysmal not great.
if a robot could reduce the chance of me getting soggy french fries and non crispy nuggies that's fine bring in the robot.
also lol plates and tables, how long has it been since you ate fast food? people eat in their car to avoid dealing with the shouting staff,dirty floor and sticky tables.
