I have mixed feelings about this sort of thing.
It's saying you don't trust your people to make the right decisions. That you don't trust them to understand the difference between a shortcut that does and doesn't matter. The fact that Chang's staff emailed them to say "hey, we've started taking this shortcut" is a reason to trust them. Any deviation from the plan, and they let him know? Great! But he thinks that if he allows good shortcuts, sometime later, they'll start taking bad shortcuts, but he'll never find out, or won't find out until it's too late? It's profoundly insulting.
But at the same time, fighting human nature is hard. Judgment will suffer while under stress, and working in a kitchen is certainly a poster child for "stressful situation". Even with the best intentions, bad decisions will be made, even if they seem like good decisions in the moment.
I still think we should strive for that trust, though. Making people stick to an inefficient process where they can't see the reason for it is how you get detached, uncreative employees.

The funny thing is I actually do think he should be caring about this. Bringing out a chicken to show customers, and either explicitly saying or even implying that they're going to take that chicken back to the kitchen, carve it up, plate it, and bring it back out is a statement of intent. If you don't do it that way, then that's dishonest in a way I'd consider really bad. If I found out that parading the chicken out to my table was just a gimmick, and that's not the chicken I ended up eating, I'd feel lied to (or at least very much misled), and that would affect my enjoyment of the experience and my desire to go back.
