I was there as a temp for nine months. There is a good relationship there and he said as soon as I am allowed to reapply he would bring me back. But as it was a pre employment test he said his hands were tied as far as letting me take another one. And believe me if I thought there was any chance I could pee clean legitimately I would have thrown a fit and demanded a retest. He said that the lab knew it was a substitution, and therefor considered a refusal, which is exactly the same as peeing dirty.
