well if it keeps working that's good.
But you also don't have a problem then, you found a good guy (at least one)
Every business out there is going to have the low end troops, be it walmart or joes lawn care, and they are all going to dip into the same cesspool for that labor. Nothing can be done about it. there is a reason why those workers are going for 10-14/hr and getting part time work, because they are all in varying degrees of suck.
