Yes toast is one of the fussiest items when it comes to travel. The steam/crisp factor always gets e'ffed up. Are you though saying that they possibly forego with toasting for delivery, if this is the case I feel that it is not the best way to go about things IMHO. If I ran a similar operation I think I might par-toast the bread before assembly to retain crispness, allow a sufficient cool down time to allow for steam/heat release. Otherwise just be like Mr. McFeeley and make it a "speedy delivery”
