There will be no fish fingers in Brexitland - the first 2-3 years of quota-free fishing will permanently destroy all UK fishing areas & imports will be trade embargoed while the UK is embroiled in 6 simultaneous cod wars
Ovens will be considerably more scarce too
There’ll be plenty of potatoes …though a lack of cheap, casual, seasonal labour to harvest them will mean astronomical prices
So maybe “oh, an expert are you? We don’t like experts ’round here, we’re sick of ’em. Shut up & eat your potato”
