Could this be one of the most costly Facebook posts ever written?

A teenage girl cost her father almost £50,000 after apparently breaching the confidentiality clause of his payout from work.

Dana Snay, from Florida in the US, told her 1,200 Facebook friends: 'Mama and Papa Snay won the case against Gulliver.

'Gulliver is now officially paying for my vacation to Europe this summer. SUCK IT.'

Her father Patrick Snay, 69, had days earlier won $10,000 (£6,000) in back pay and a settlement understood to be worth $80,000 (£47,800) - according to the Miami Herald - from Gulliver Preparatory School in Miami for age discrimination.

But the school refused to pay up, and a judge backed its stance, on the grounds that Mr Snay was not meant to have told anyone the details of the settlement.

Mr Snay, who is now a headteacher at another school, could still appeal at Florida's supreme court.
