After advertising his services to morning rush-hour traffic on Tuesday, Mr Crosbie was offered two days' work as a casual fish-packer at Blue Water Products.
Halfway through his first day, Mr Crosbie said it was a busy place.
"They're very, very efficient. They don't let you stand around for more than a second. But, hey, that's fine. I'm here to work."
Mr Crosbie said he had received hundreds of texts of support, including one from Australia.
However, there had been "no real job offers as yet".
"The only odd one I've had is a woman rang me and said she was an employer and she would give me a job if I shaved my beard off."
That was something he would not be doing.
