I don't quite understand why the 'hot sandwich' tray still has butter and a bread plate, but I suppose it makes the tray look full! Or maybe it's there to remind passengers of what they previously had.
Perhaps
Littlegirl or another crew member would be able to answer the following. Will the new Club Europe hot sandwich be heated in the same oven as the Euro Traveller bacon rolls? That would surely simplify the process greatly, as I presume the old set up was that CE meals were heated in the front galley, while ET hot snacks were heated at the back. Is that correct?
