I think you've got it backwards. Whether the glass ended up in the dishwasher or not didn't matter much to him. It mattered a lot to her and instead of putting in the bit of effort, he tried to justify to himself why he shouldn't have to.

My husband has a thing about making phone calls. I've got other crap I put off for similar reasons, but phone calls are not an issue for me. So when a call needs made and I have the information needed, I'll do it and save him the stress. Not a big deal for me at all, but it takes something off his plate that he doesn't like to do.
