The other day, I was telling a class how in the 90s you could win a fiver/tenner/20 pound note by finding it in a packet of crisps. They were having none of it... I had to Google it to prove it actually happened 🤣

In the early-2000s medical situation comedy Green Wing, the X-Ray machine operators are deen scanning huge numbers of crisp packets, looking for the concealed banknotes.
