I hate giving urine samples. When I was in the hospital last year (wow it's been a year already lol), I had to give my doctors regular samples so they could see how my body was metabolizing the cocktail of drugs I was taking. The worst part is that instead of a cup, it was a test tube! Do you know how hard it is for a girl to pee into something that's only an inch wide? Not to mention that I just had surgery too so I was in pain.
I've never given a urine sample for a job or anything else before, but I can only imagine that's it's just as unenjoyable.
