The women treat him like shit? What was he optimizing?

Well he was the only male except for me so there was noone else to treat him badly. He was just taking over the invoicing that noone had time for anyway so I have no idea why they were treating him so bad. The ones that were doing the invoices were always complaining that they had to do that on top of their normal job. Some people just can't handle new people showing up and think it's a threat to them. Turns out they were right to feel threatened though, the company shut down the whole branch a few years later and moved everything.
