Me thinks this could end up biting you in the ass......
Think about it ..... They know exactly where they picked him up, and who bailed him out.... what's to stop the all knowing Immigration Officer to 'camp' out by your place on his day off just looking for your worker, and when he shows up calls his buddies from immigration to do a 'inspection' and have their hand out, because they know that you have already paid once, why not again, but this time directly to him and his buddies, where they get the cut and not some hire ups....
My Thoughts, Not Yours....
