Yes - the usual breakfast tray set up for everyone in F (regardless of pre-order) on that route is the fruit dish, yogurt cup, croissant, plus the selected entree. Only the entree is what one pre-orders and your was likely vegetarian non-dairy. I think passengers with special diet requirements should carry “just in case” rations.

Sometimes the FAs don’t tray the yogurt cup if one orders the yogurt smoothie.

Definitely doesn’t need to be in GS thread.
