Hymie - "Rather than ‘small print’, perhaps I should have said the insurance document terms and conditions printed in a smaller font."
You could of course have said that - but then you'd just show yourself up as being wrong.
A contract of insurance doesn't contain words with a smaller font. Some words may be written in a bold type face or italics, and if they are this means there's a definition of what that word means in (funnily enough) the definitions part of the contract.
If some people can't read plain English, then that's their issue, and can't be blamed on the insurance (frankly, if anybody cannot understand an insurance contract aimed at consumers, then they're as thick as a brick).
