I would assume micky’s hamburger’s come frozen. So he’s suggesting they “defrosted” it an served it?
Given their current production procedures, there’s no way this wasn’t deliberate.
From my recollection of working there several centuries ago, they're frozen rock-hard. You put it on the grill and start a timer, which has a beep code for turning it over and another for when it's ready to take off the grill. It's pretty hard to screw it up.
they are frozen patties. may have nuked it a little or put on grill just long enough to thaw it to raw.
I’m guessing he doesn’t know how fast food, except a few, is prepared.
