Probably not. While it's trivial to ensure that exactly N coins are given
back, this is rather difficult to achieve with notes. Bank ATMs *can* do
it, but they need rather expensive machinery *and* are using specially
prepared ("ironed") notes. Ticket machines typically give back coins they
got from previous customers, and I can't see how this should work with notes.

Sainsbury's have "self scan" machines in some stores which allow
you to scan your own shopping at the checkout. These accept notes
and give notes in change so it is being done. It might not be the
same stock of notes but that doesn't matter to the user.
