That said, if I were still poor, I wouldn't want to keep my stuff in the freezer at one of these pay-per-minute cafes, because it'd be gone by the next time you got to it. I also assume that they lock up at night, so I'm not really sure how this'd help vagrants all that much.
However, if you happened to be lucky with the other people in the cafe (i.e. no-one being obnoxious or noisy), then it makes a ridiculously cheap coworking space.
Although it depends on your oven if gas or electric, your time and effort, how much power a bread machine uses. The oven makes bread far better than a bread machine but a bread machine is better than mass produced, sliced, preservative laden white bread.
But you could time it so the bread is baked when the oven is used for cooking supper.

The machine is useful if you're not good at/willing to/able to plan a bit. You have to do a number of steps on a schedule when baking by hand, there's only one to worry about with a machine.
It is very little total work (15 minutes max) and makes great bread, but it does require some planning ahead because of the long rise time.
