Cockroach Cuts @Metro North Railroad

Today while on my way home from work I saw the bottom half of a cockroach lying on the platform.

It looked neatly sliced.

Incompetence @Client

I'm doing a summer job for a firm in Midtown. Sometimes I handle Accounts Receivable. This past week my boss passed off an accounting puzzle.
It's this woman who works for a very big client of ours. She refers to herself as an "Accounts Receivable Specialist."
I received a list of checks she'd cut us in the past 3 or so months and an email stating which invoices she thought they corresponded to. Questions marks were included.
If it's your job, shouldn't you be good at it? If her job title is anything to go by, THIS IS ALL SHE DOES.
I cranked some numbers til I figured out what I thought she meant. Basically, I solved her job.
I'm the best at stuff. Not to sound overly self-congratulatory.
