I’ve seen this several times on UK social media. There’s a video of one of the little kids shouting at a local. Horrible bloody family by the sound of it. The accent is definitely Irish traveller (I’ve worked with loads, there’s a large community near me).
One of the girls has nicked $55 worth of stuff from a garage shop, they’ve littered the beach and refused to pay due to ‘insects in the food’ for pretty much every meal they’ve been out for so far. The local mayor said he accepts you might sometimes find something in your meal but not every bloody one! I am, sadly, unsurprised. It’s also on European media.
