Usually we'll do anything to avoid the nightmare of Tesco's self checkouts, but for one 17 year old, choosing to forgo human contact at the supermarket resulted in him being able to walk off having "paid" for his Jaffa Cakes AND a bonus of 41p more than he came in with.

Like any 17 year old would, Josh took to Twitter to share his lucky break with his followers:

Just bought some Jaffa cakes in tesco for 59p so paid on self service with a pound coin, gives me £1.41 change, cheers @Tesco

Of course, Tesco wanted to know which machine in which shop had made this error and replied with:

@JoshKnight98 Hi Josh, thanks for getting in touch. I expect you to enjoy those Jaffa Cakes since we're paying you! 1/2

— Tesco (@Tesco) May 23, 2016

And duh, Josh loved those cheeky free Jaffas

@Tesco they were spot on

— Josh (@JoshKnight98) May 23, 2016

But Dafydd from the Tesco social media team wasn't giving up without a fight -

@JoshKnight98 Could you DM me the store so I can get the till checked? If you have your receipt, could you send a pic? Thanks - Dafydd 2/2

— Tesco (@Tesco) May 23, 2016

But everyone knows, snitches get stitches - even when a machine was the perpetrator:

@Tesco I'm not a grass sorry

— Josh (@JoshKnight98) May 23, 2016

There aren't many clues as to the location of the jackpot self service machine, if you were planning on hunting it out yourself, but Josh's Twitter bio says he lives in Bristol, so who knows?
