Even the most enjoyable day out with friends and family can descend into bickering, but surely Disneyland - the Happiest Place on Earth - would be the ideal setting to dispel lingering tensions.
Well, as this shocking footage shows, even there things can sometimes get a little bit out of hand:
The incident took place in Mickey's Toon Town, outside the Goofy's Playhouse attraction, at Disneyland in Anaheim, California, back in 2019.

And perhaps needless to say, no one comes out of it looking good in the slightest.
As you can see in the clip, a woman in a white tank top, a man in a white shirt and a tall man in a pink shirt square up to each other.
An argument between the group escalates, with the tank top lady spitting in the pink-shirted man's face.
He responds by slapping wildly at her, before squaring off against the white-shirted man.
They engage in a little shadow boxing, before breaking up. Pink shirt goes at the woman again, before thinking better of it and walking away.
Where are security in all this, you may be thinking? No time for that, though - the man in the pink shirt isn't quite done.
In scenes we've chosen not to show, he goes over to the woman in white and starts pulling her hair, before bystanders intervene.
It all looks like it is rounding up, with the pink-shirted bloke walking away, only for the white tank-top woman to start screaming at two other ladies, getting into a physical altercation that leaves one of them sprawled out on the deck.
Pink shirt man comes back and starts slapping the white-shirted woman in the face, leaving her flat out on the floor.
He shouts: "I'm going to jail tonight!" and struts around, before then turning on a third woman and punching her repeatedly.
Eventually, a gang of fellow Disneyland visitors manage wrestle the pink-shirted man to the floor.
Security eventually arrive, but nobody apprehends the pink-shirted man and, at the end of the video, he is walking free as security make little effort to stop him, including him going back to shout at the women he had punched in the face several times.
Disney say that the participants were ejected from the park.
Following the incident, those involved were named as Avery Robinson, from Las Vegas, and his sister, Andrea Robinson, and her husband, Daman Petrie, from Compton.
Avery Robinson was sentenced to 180 days in prison after he pleaded guilty to one felony count and multiple misdemeanours in a plea deal with Orange County prosecutors.
His sister and Petrie failed to turn up to appear before Orange County Superior Court Judge Scott Steiner and were named fugitives from justice.
Andrea Robinson was charged with five misdemeanours, and her husband faced one misdemeanour count of battery.
