So one minute you are out of work and desperate for any paid employment - you get given an opportunity with a new company, and 5 minutes later you drop them when something better comes along ?
You know if I had employed you I would be pretty irritated at you lack of loyalty.
There might be more to the story - but as you have announced your good fortune with considerable glee (no word of thanks to mtcash) and this is the only detail you have given....
Lets face it you did not even have time to change your job hunting sig !
