what about this scenario??? I'm sure this has happened before (although it
wasn't me. honestly, it wasn't me).

What about all the fast food pranksters not using a radio?

I'm talking about the people who drive up to the drive through menu board in
their car, then order a bunch of food, and then instead of driving the rest of
the way through the drive through, they simply pull out and drive away, so that
the car behind them gets charged for all of the food that they ordered that the
car behind them did not order.
