The only complaint I have is that when there isn't space, she forces it in anyway and then you end up with mangled, frozen slices that don't fit in the toaster.
If you have the space, a second deep freeze is a game changer. You can often find them for cheap or even free, the ones from the 90s seem to last forever.
I just _know_ she'd love to have a chest freezer (runs in her family I think); alas, we live in a London apartment, space is one thing we don't have.
On a side note, with energy prices (which are typically high in the UK compared to some other places) I'd be loath to use an "old" freezer. We once rented a place, and I found their circa 80s freezer user more electricity than we did for the rest of the flat.
I've always been one to prefer newer, more energy efficient devices even at a higher initial cost (it's somewhat of a hobby of mine to see how energy efficient I can make things in my home), it's times like these where I feel it's actually paying off.
