Now, that's talking fast. Really fast...Okay, so now the new definition for 'fast food' is anything that can be cooked in under 20 minutes, eh?
When I worked at McDonald's, we were supposed to be able to cook a customer's entire meal in about 45 seconds, on average. They have grill with a clamp (like a giant George Foreman grill) that allowed us to grill about 32 hamburger patties at once, without flipping. Then, you would store the patties in a warming oven until you needed them, which meant you could assemble a burger really, really, quick. We were supposed to replace the patties in the warming trays every 15 mins (which isn't that bad, if you think about it).
...But we never did... (Which is pretty bad, if you think about it*)
Anyway, point is 20 mins isn't really that fast. At actual restaurants (as opposed to whatever mickey d's is) I have worked at, they can easily make some meals in 10 minutes, especially if it is something like stir fry. I think a better definition of fast food is food cooked fast enough to merit a drive through. No one is going to wait 20 minutes in a drive through line.
What if they had "slow" food restaurants? Like, where every single meal took multiple hours to make, but they made the wait worth the while? For the last hour before your meal, you would not be allowed any food. And for the last ten minutes, they would just waft smells across your table, making you more and more hungry. For the last minute, they would just wheel food past you, but never stop at your table. Finally, they would have the waiter bring out your meal, and it would look so delicious, but then he would trip and fall.
And just when you thought you would never get to eat, they would bring out a second meal, one that looked even better than the one before, hot steaming, just glistening with flavor. And they would set it in front of you, but you wouldn't have any silverware. And then the waiter would whisper to you, that its okay, just dig in. Just grab at the feast with your bare hands. Just tear it apart and shove it into your face.
And tell me, would that not be the best meal of your life?
*If you ever eat fast food, I recommend not thinking about it.
