Hmmm... as for assembly food, in the U.K. we used to always grumble about it. When I was young we used to queue to stand in a tent to have food plopped into compartmental Trays . A careless server meant that you had some gravy in your desert .. and for the tables were made for an adult to stand next to and eat , so if you were a kid your meal was level with your nose !
Over the years the service improved but the food didn’t. We still grumbled but then they took it away and we had nothing bar what we could take. Then we kept saying how we wanted the hot food back !
