Its not really getting cold, a big part of the resting is about the internal temperature increasing (at the cost of the outside dropping from 80 to 50 celsius, which is still more than warm enough)
There’s considerable difference between food sitting out for nearly 20 minutes and food served immediately after having been cooked on a cast iron surface, or a side out of a stainless steel pot.
I mean there’s no comparison. Same with fresh bread rolls out of the oven.
People are just overwhelmingly OK with literally cold food.
