The use case is bagels or pizza across the country? If you don't eat those within the hour they're not good anymore. Other than that, I really can't think of a situation where I would be willing to pay ridiculous amounts of money for cold food.
Blasphemy. Pizza is best when served cold the next morning.
This is a very New York/New Jersey perspective. And I respect that your palette is too refined to ever accept a non-fresh bagel.
But there are people who live outside of NY/NJ, who don't have a bagel shop down the street. And you may be surprised to learn that some of us love bagels, and will even eat a toasted bagel. I understand this is an abomination no New Yorker or New Jerseyan would ever touch. But I can assure you many of us with lower standards get quite a bit of joy out of a good re-toasted bagel. If a bagel is sliced and frozen shortly after baking it actually keeps fairly well.
Again, I can't recommend you ever try a toasted bagel yourself. You would certainly be disgusted by it, as any respectable New Yorker would be. But for the rest of us they can be quite enjoyable.
