Dear, dear Scumbucket, don't get your tail into a knot about this. You are performing very valuable service when you are on this sort of duty. This time in a human's life is a crucial one indeed, Scumbucket, and anything can happen.
Extreme vigilance is the rule.
You will never know the true meaning of frustration, dear Scumbucket, until such a moment. Furthermore, Scumbucket, do not be blind to the other opportunities available to you at these places. The staffers, overwhelmed and underpaid, can be made callous and uncaring, and effect the most exquisite tortures completely unawares, as they try to just survive another shift. And you, Scumbucket, get to snack on all the grief, terror and bewilderment being experienced, like a human in front of his refrigerator sampling leftovers at midnight. I almost envy you.
