Answer:
that accommodating Agnes would cause the restaurant undue hardship.
Step-by-step explanation:
Undue hardship states that it is the situation in which a person exempt himself partially or fully in performing a legal obligation so that the burden could be avoided.
According to the given situation, Agnes who is a waitress is not able to work more as she suffers from anxiety attacks. So, from this, the owner fired her and gives her work when the restaurant is not busy enough. On the other hand, other waitresses are not felt convenient as they found difficulties and increased expenses.
Here, Under the Americans with Disabilities Act (ADA), Agnes suit a file against the restaurant, so, in this case, the restaurant will give facilities to Agnes which causes undue hardship.
