You know when you're sitting in a restaurant and you go to shake some salt on your food, but someone unscrewed the lid, so all the salt pours onto your food? This is my life.

My wife almost never puts the lid back properly on anything. If it's a threaded lid, she'll (usually) crossthread the lid so it's not properly secured, but often she'll just set the lid on top. For things like Tupperware, she'll typically press the lid onto 3 corners and leave the last corner unsecured.

Condiments and drinks get spilled needlessly; foods dry out, get moldy, or absorb odors unnecessarily in the refrigerator or get stale in the cupboard; etc. She never spills any of it as far as I know; she must assume that nothing is properly closed. She is not bothered by any of it, whereas I don't even like having peeled garlic and open butter in the fridge because of the absorbed smells...

How can I ask her to fix this issue? I have talked to her about it before, but usually after I just spilled something or made a mess because her lid skills, so I'm already irritated. She knows she does it and that it bothers me. I am more exasperated than confrontational.
