Last year Kevin Colvin lost his job as an intern at the Anglo Irish Bank in Boston after he emailed his manager saying he needed time off to go to New York because of a "family emergency". But his boss discovered photos on Facebook that showed Mr Colvin at a Halloween party drunk and dressed as a fairy. In an email reply his boss attached the photo and wrote: "Thanks for letting us know - hope everything is OK in New York. (cool wand)".
