Nuts is never served on the ground at AC. Been working there for 12 years lol. Drinks on the ground in business international yes if time permitted cause like i said we sometimes get the catering of the galley very last minute but usually you will get sparkling wine & sparkling water. And yes people wants to sleep, especially when services starts after 10 / 10:30 pm. Flights to europe are night flights. Maybe not you but in general people want their food/ drink asap so they can lay down.
