I understand the rest, but an otherwise capable person with a sick family member does not clear the bar for competent? Saddening if that’s where we are as a society.
I think the key part of that sentence was "...and just needs an advance", implying that they're going to take the job, ask for a cash advance for a (possibly fictional) sick family member, and immediately quit.
It’s hard for some people to understand that situation until they are in it. Unfortunately.
