I’m going to play a little game, involving a £5 note.
I scribbled a little message on a £5 note which I’ve recently spent. This message instructs the new owner of the £5 note on how to let me know they’ve got it and where they got it from.
In theory, I’ll be able to track the £5 note and see where it ends up. If you want to follow the £5 note too, save this link as a bookmark and keep checking it out.
