Agree 100% Joe, been through the same. A very difficult gameplay here because asking or demanding a daughter adjust her expectations is tricky. Push too hard and she'll just go teenage contrarian for years.
And also do bear in mind that she's still forming a personality so it's normal to have to rub off a few rough edges before a decent, rounded personality arrives.
All we did in similar situation was to point out the logic of getting a weekend job and provide a bit of help with jobhunting. Weren't too aggressive about it. Also we gave cash bonuses for GCSE results (mercenary I know, but it worked).
Both daughters have to pay for their own clothes, social life and when it comnes time for that driving lessons and insurance.
