Erm... we haven't actually left the EU yet

call it calm before the storm or whatever you would like. Anyone who goes on holiday to the states or euro zone can already feel a difference. Your shopping bill will also take a hike after Christmas, if people have to pay more for essentials then there's less in the system to buy other things, less buying other things means less manufacturing, means less taxes and so on.
Of course no one knows 100% what way it will go. I'm firmly in the make the best of it camp now, it's 99% happening so why would I want the UK to fail after brexit? I would much rather to be proved wrong than it to be a disaster just so I can tell a few people on here 'I told you so'. But that is going against all logic as far as I can tell.
