That is why we don't map the actual rating, only the id.

Hopefully not £50 notes for some time yet, they are just about
impossible to spend as few places will accept them. £20 can still be
awkward to spend.

Surprises me that in the eurozone I often get €50 notes and nowhere
bats an eyelid.

The local Barclays dishes out £5 notes, a bit of a pain as you get lots
of them and have to be careful to separate them. But that is closing
soon.

I have never had £5 notes from the Barclays in Shrewsbury.

Banks (and with them ATMs) are currently one of the most volatile
amenities which we need to keep on top of to prevent the map becoming
outdated. That is a big enough job for mappers without worrying about
what notes it dispenses.
