Don’t panic. Do not try to spend it. Take it to your local bank or the police. They’ll take it out of circulation and may ask you where you got it. It’s a bit awkward, but it keeps the economy safe.
The worst thing you can do is ignore it. A fake note that sits in your wallet is like a bad penny—it’ll just turn up at the worst moment. Deal with it quickly, and you’ll feel like a responsible citizen.
And hey, if you really want to be the hero of your local café, show the barista what to look for. A little knowledge goes a long way. You’ll become the cash-wizard of your high street.
So next time you pull out a twenty, don’t just trust it. Give it a quick squeeze, a tilt, and a glance. It’s a small habit that saves big headaches. Plus, you’ll have a great story for the pub—and a real note to buy the first round.
