It comes down to logistics. Maybe I'm a smaller restaurant, and I want to serve BBQ or fresh bread. Might not be feasible for them to smoke a brisket every day if they're not a brisket place, but you can definitely freeze some brisket and bring it back to life in pretty good quality. It doesn't improve it, but it lets a restaurant serve something that they otherwise couldn't. Same goes for fresh bread. Maybe they wan…
Yes, these are examples of people maximizing for a variable other than quality. The linked study indicates that the freeze-thaw cycle has significant negative effects on the quality of ground beef.

Freezing food has a stigma that it doesn't deserve if the freezing and thawing is done with care. As I mentioned before, the best sushi restaurants in Manhattan all freeze their fish and store it in extremely cold freezers, and there's no significant detriment to quality. If Shake Shack wanted to do so, they could freeze their patties, and they'd still have one of the best restaurant burgers out there. They certainly would not be freezing their meat in the way that was done in that burger paper, nor would they be using meat of that quality.
