These diamonds were hand-picked. But we can't promise that the picker washed his hands first.
"Hey Kenny, can I have a word with you, please?"
Sure boss, what's up?
"I couldn't help but notice that you didn't wash your hands before returning to work."
Oh, yeah, I uh ...
"Did you or did you not see the sign?"
Uh ... what sign?
"This sign right here."
MUST WASH HANDS
BEFORE RETURNING TO WORK
Oh. Yeah, sorry. I didn't think it ...
"That's right. You didn't think. And now all those hand-picked diamonds are tainted with the germs of those non-hand-picked ones you've been sifting through over there. DISGUSTING."
I'm sorry, boss, I ...
"Tell it to the poor customer who will be enjoying their hand-picked diamond, completely unaware that it's been TAINTED BY NON-HAND-PICKED DIAMONDS."
I think I should just go.
"Yes. I think that's best for everyone."
Can I take this pocket-full of diamonds I've been hoarding for weeks?
