I don't mind if the teenagers at a restaurant can't accurately predict when an order will be ready.
I mind that there's no system to handle someone who arrives before their order is ready.
Once the food is ready, it goes to the waiting area where the cashier will look for it when a customer arrives.
But if a customer arrives before the food, the food will sit in the waiting area until someone goes looking for it.
But hey you guys I'm not trying to save the world; I just like pizza.
