NononNO. No one will be able to BUY an appliance with a 13A plug in it
unless their ID cards show they have 5 science A levels.

Then the masses will need 5 science A levels - and they can't be denied.
So the A level certificates will come with the appliance and ID cards will
be updated at the checkout. Of course the checkout operator will ask three
testing questions to validate these qualifications:
Do you want to pay Cash? y/n
Do you want to take it with you? y/n
Do you want our extra warranty? y/n

And for foreigners (and those without an id card) the checkout operator has
an Anybody@Anywhere card which also confers VAT exemption.
