Christmas lovers officially kicked off their festive countdown this morning by watching the new John Lewis advert.

And while most enjoyed the heartwarming clip, people who know their bus routes were left a tad confused.

Bus spotters highlighted a rather embarrassing mistake in the highly-anticipated ad - which has already gone viral.

The department store's ad was inspired by random acts of kindness carried out during lockdown in March.

It begins with a young boy whose football gets stuck in a tree.

His friend, a little girl with broken glasses, steps in to help him, using a heart umbrella to knock it down.

This sparks further acts of kindness as the little boy helps a snowman fly away, who then helps a family get their car going.

Bus enthusiasts aren't impressed by the advert

But viewers weren't impressed by the next scene - although the actual exchange was very heartwarming, as a kind-hearted nurse repaired the little girl's specs with a heart-shaped sticker from an apple.

The duo were travelling on a 222 bus which said it was heading to Tooting, but in real life runs from Uxbridge to Hounslow.

Bus spotters took to social media to share their disappointment at the error, which left some people fuming.

The John Lewis ad highlights the kindness of the British public

One viewer moaned: "The John Lewis christmas ad is sending me, why the F*** IS THE BUS GOING TO TOOTING??"

Another commented: "That John Lewis ad is cute providing you can get past the fact there is no 222 bus to Tooting," adding: "Which obviously I can't."

A third tweeted: "My only criticism of the john lewis advert is there is no 222 to tooting."

A fourth blasted: "I'm afraid I can't endorse this advert because I've ridden the 222 countless times and it goes nowhere near Tooting."

Another eagle-eyed viewer wrote: "FACT CHECK: The 222 runs from Uxbridge to Hounslow and doesn't go anywhere near Tooting. Did you really think we wouldn't notice @johnlewis?"

But others shared their love for the advert, with one writing: "Anyone else seen the #johnlewischristmasadvert It is so what is needs right now.

"A little bit of kindness & love really does make the world go round. So here is a little from me."
