So if a few families come in at once using this philosphy, theoretically we can have a restaurant full of people sitting down and not eating while 20 people have food in their hand and nowhere to sit.
This is probably why legitimate restaurants seat you.
It's a shark move cause it gets you what you want faster, and a #### move cause it screws other people who were there before you who didn't want to be jerks to the people who got there before them.
It's efficient for YOU, but royally inefficient for everyone else. It's not really about being smart. This isn't the business world. This would be the kind of practice that gets you locked up in the business world.
That said, not even sure if I would do it or not. Probably depends on how big of a hurry I am in. Everyone is allowed to be a #### sometimes, right?
