Final answer:
It is not acceptable for a dishwasher to wash their hands in the three-compartment sink.
Step-by-step explanation:
After handling dirty dishes, it is not acceptable for a dishwasher to wash their hands in the three-compartment sink. The three-compartment sink is typically used for washing dishes and utensils, not for handwashing. Handwashing should be done in a separate sink or designated handwashing station to ensure proper hygiene and prevent cross-contamination.
