I don't quite get the logistics. The photo in the article is of the kind of trays that substitute for a plate, with compartments for different foods. I haven't been to that kind of cafeteria in many years.
But the buffet restaurants I do visit serve on plates, and provide trays to carry the plates. If you have a main dish, a salad, a dessert and a drink, but no tray, that's multiple trips to the table.
So trays don't feel very optional to me. What am I missing? Are people not minding multiple trips, doing fancy balancing acts on the way back to the table, or combining everything on a plate?
