Here in the UK there seems to have been a shortage of £5, £10 and £20 notes from cash machines lately - no idea why?
The outcome of this was that I received a £50 note instead!
Although some people may be familiar with these they are not something that is in everyday use here at all. I have only had about half a dozen £50 notes in my entire life and that was many years ago when I lived in London. This is one of the new polymer notes which were introduced in 2021 and even has the first AA serial number - so do I keep it or spend it???
