Mostly it reeks of asking the other partner to finish the job. I'd wager this guy didn't do the dishes more of than not either. A lot of men genuinely don't help out around the house and don't understand why it upsets their wife so much.
From a gender roles inversion perspective this would be like if your wife bagged up the trash from the bin and then just left it next to the bin instead of taking it out. So now you have a dirty bag of garbage on the floor until someone decides to take it out. Almost a worse situation than just leaving the bin full.
Regardless of whether an issue is petty or not, if a spouse indicates it bothers them for whatever reason, and the other spouse just basically ignores it, this is a recipe for disaster.
