Had a bad day at work yesterday about 10.30 in the morning had a prisoner (Prison officer) in for a mandatory drug test as he was under suspicion of using drugs. Said he could not provide and was given some water and put in a holding room. About 1/2 hour latter said he could now provide and was given the sample bottle, we could see that he had a bottle in his hand and asked him to hand it over, at this point he threw the urine in my face. As I said bad day at work.
