€5 banknotes are a precious commodity
.
A friend of mine started to collect €5 banknotes for weeks before her departure for her continuation of the
Camino Frances, and I started to follow her example. I think that I had collected 15 of them or thereabouts when I left for Spain. Of course, you can do this only when you happen to live in the eurozone as we do.
Someone mentioned that some ATMs in Spain allow you to chose which bills you want. I don't know how common this is in Spain nowadays. Where I live I can do this now - it was not possible when the Euro was introduced but that's a long time ago. These days, I never get anything higher than €20 banknotes, and of course I pay as much as I can in cashless form, whether at home or on Camino.
