The frequent grocery shopper (2-4 times a week) = Hunter-gatherer man. Likely high T, not simp-like, very adaptable to his environment. Likes his grocery food fresh just like if he was killing an animal for a fresh meal.
The once a week grocery shopper = Hunter-gatherer in transition man. Average T, somewhat simp-like, somewhat adaptable to his environment. Likes some of his food fresh but freezes some things and doesn't mind trading convenience for freshness.
The once a month mega grocery shopper = The women and domesticated men. These are the types to freeze everything, including bread, because they want to frequent the grocery store as little as possible. They say it's to save money at Costco but it's really because they feel the need to be incredibly stocked up on food because they aren't a hunter-gatherer. This is the female-coded style of grocery shopping. Men who shop like this have given over control of the food to their woman or they have low T, are simpy and somewhat like a woman themselves.
Bro, have you never seen inside a single woman's apartment? Despite all the talmudvision commercials claiming the opposite, the average woman is a disorganized slob.
