Sorry guys, I had a call. I honestly don't think it's that weird and hopefully an example of our grocery list makes sense. This is obviously won't matter anymore now that we have a combined account. But this is usually how it would go.
Mrs. Wacky: Protein bars, celery, carrots, salad crap, chicken, la croix, wine
Wacky: steak, steak marinade, cheese, potatoes, popsicles, beef jerky, etc.
If I feel like a carrot at night, I help myself to a handful. If she wants a jerky snack, snack away. I guess the person who we know is going to eat it the most usually gets said item. I know it sounds and looks weird, this will no longer be an issue.
cf3: Sometimes I sneak some gummy bears in her groceries. I know she wants them too.
M^2: Of course I carry her groceries. I'm a gentlemen.
