Rising food costs, rising production and material costs, supply chain disruptions, increased costs and bureaucratic red tape for imports and exports, reduction in food standards, significantly decreased mobility, businesses moving their operations out of the UK, the impact on the NHS, the apparent Tory strategy of just winging it up until now. There's many more, all detailed at length in here, often from people who are already directly feeling the effects.
For a man who apparently voted remain, I'm surprised none of these entered your orbit and even more surprised that you're happy for Boris and the Tory circus to take the reins on this. I'm not going to lie, your "let's get behind Britain" and "remoaners still haven't accepted it" shtick has all the vague, unquantifiable hallmarks of a Brexiteer than a remain-voting Labour Party member. In fact I'd say that claim is about as real as Petes financial director friend and his sudden Brexit epiphany.
