In Europe they think nothing of 50 euro notes, and if you draw money from a cash machine in Spain or Italy, say 200€, you'll invariably get three fifties in the mix. Yet we don't like those damned fifties here. I've only ever had one, from a Barclays cash machine in Padstow that had run out of smaller denominations. There was a near-insurrection in the street as more and more customers received these unwelcome items!
