There is a special place in heaven for those people who choose to become caregivers for the elderly.
There is a very special place in hell for those people who choose this profession, take their charges to my restaurant, take their charges to the restroom, and leave an enormous, disgusting mess all over the bathroom.
I understand that it is gross to clean these things up. But it is your job, as the caregiver, to do so. Or at least have the decency to alert the management, so that our unsuspecting patrons do not stumble upon said mess, and storm angrily to the counter to complain to me about it.
If you feel uncomfortable doing this, you ought to look into another profession, which does not include cleaning up these sorts of messes. I myself have found such a profession.
Which is why, when my manager tried to guilt me into cleaning up the mess, I politely declined, telling her that I do not get paid nearly enough to deal with this kind of, well, crap.
