One of our local pubs has re-opened as a 'pub food' take away / home delivery. So sausage & chips still available, not sure if you still get a basket though.
I do have Prime, and I did subscribe voluntarily. But it was after Amazon sent me an email saying 'do you realise you spent £155 on delivery in the last 12 months' ...
The ECHR is not part ot the EU. It's a totally separate institution. Teresa May might hate it (I don't really understand why a rational person would) but leaving the EU won't affect our membership of the ECHR.
The UK government fought hard against Brussels plan to impose the abolition of intra-EU roaming charges. Brexit will be a good opportunity to allow them back.
