@DallasGuy75219 You may laugh but it really depends on the executive chef. Some years ago the Grand Princess had a world class executive chef and he put the time and effort in to train the people working below him in how to efficiently cook to order. (He left to run his own fine dining establishment on land). Other executive chefs may take the lazy route and not bother to train the staff to perform anything other than batch cooking.
Getting back to the Grand when the world class executive chef was running the galleys it may have taken longer for food to come from the kitchen but it was really high quality.
Once he left the Grand meal times in the MDR were different and the food appeared much more quickly at the table but the food was of lesser quality.
Note I have taken a tour of the galley on the Grand with the aforementioned executive chef.
