Ok:
* Shelves have been bare several times because of the lack of veg/fruit pickers. It's and you would have seen it in the headlines and the photos of supermarkets.
* There have been drug shortages too. Once again, it's been all over the news. The Daily Mail blame the EU for it - so, basically, it's because of Brexit but not the UK's fault for leaving. How's your HRT supply at the moment?
* What have holidays got to do with Brexit? If you've got a passport and have the finances, you're good to go mon frere.
Apart from all of that - good points, well made.
