I think you’re looking for the difference between fine dining and nouvelle cuisine / haute cuisine. Think of it like the difference between a nice steakhouse where the server essentially takes your order and gives you a plate, and one of those Instagram dinners where they serve your dessert in hollow chocolate balls and serving is a more involved and delicate process because of the nature of the food you’re serving
Sounds like that server deserves a generous tip, I hope you take good care of them :)
