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.
Not everyone is impressed.
Some people were REALLY unimpressed.
While others thought they might be losing the plot.
An automated till occasionally saying "HO HO HO" is, apparently, creepy.
Of course, some shoppers love robotic shop assistants being merry all day long.
But for many, the realisation is just dawning that we're all going to have be wished a "MERRY CHRISTMAS" every single time we use a Tesco self-service checkout.
Still, at least it makes a change from what self-service machines usually say.
However, there is a cure for all self-service noise-related problems: There is a mute button and you can TURN OFF the sound.
