Something weird is happening in a supermarket near you.
Something not normal at all.
BuzzFeed News tested a self-checkout in London's Soho, while buying a BLT sandwich that was no less than 32% of our daily recommended salt intake. Shoppers went about their business as normal.
There appeared to be no noticeable mental strain on the staff who have to listen to a dozen machines saying "HO HO HO, MERRY CHRISTMAS", all day long, not quite in unison.
It also plays "Jingle Bells" while you're scanning stuff.
Tesco confirmed to BuzzFeed News that the festive greeting is being added to ALL self-service checkouts by 10 December and they will stop saying it on 27 December.
Tesco also pointed out that only customers who scan their Clubcard get the jingle bell noise.
