When They’re Not Pro Pronoun

I’m a woman with a pixie cut. I like to have an undercut and spike it up to keep me cool at work. Both members of a married couple have grabbed an item they only need one of. He hands me the extra one.

Husband: “Put this back; we accidentally grabbed two.”

Wife: “You should do it because it’s our fault and she’s clearly busy.”

Husband: “That’s her job.” *Pauses* “Or his or their job… I can’t tell anymore these days.”

Me: “I’m a woman.”

Husband: “Oh, good. I can’t deal with pronouns today. We didn’t have pronouns back in my day.” 

I just looked at the wife, who face-palmed and forced the transaction along before he could say anything else.
