Makes sense in economics 101. The reality is, the Instacart guy doesn't give a shit and will provide bruising as part of the service of schlepping your crap for you. The in-store shoppers don't really care either.

The explanation that you're providing is really a rationalization for paying more to procure an inferior product. You're always going to have wastage of perishable items. It's much cheaper and sensical to avoid moldy strawberries, close to date meat and dairy, etc by shopping yourself, or hiring your own casual labor without some intermediary subtracting value.

All of these services are hiding costs through VC largesse and exploitation. You can literally get more for less by just hiring a housekeeper and having them pick up stuff for you, but nobody does that because the costs are "above the line", and it feels less nouveau riche and more clean to have some service exploit the poor sap picking your banannas rather than talk to a human.
