The Minghams really are the antithesis of 'Center Parks' people, aren't they?! If they have even an ounce of self awareness they must surely feel out of place. He may be wearing his bestest baby poo 'Dad chinos' and she has her knock-off Birkenstocks but with all their chavvy ways (actions too, not just looks) they're still never going to blend in.
And as for 'Cidergate'....personally I think it doesn't really matter if it's the alcoholic or the
non-alcoholic version, it's still not a good look regardless.
Sorry but I wouldn't want my teenager drinking Koppaberg from a can, in a kids play area, giving the perception that they're drinking alcohol in public (even if they actually weren't), especially somewhere like that. People would definitely get the wrong idea and I'd be embarrassed, quite honestly.
Lazy, you could always try swapping your daughter's Koppaberg for a Kombucha or Kefir drink, if you want to fit in with the wholesome middle class Mums!
