It may depend on the store. My local publix trains it’s employees like Chick-fil-A does, and they probably would be offended if you didn’t let them help you.
The baggers at my local food lion (if there is a single one in the store) are offended that they have to help you at all (probably because they’re expecting you to be the fifth person today to come back in the store demanding a refund for the one cracked egg in their dozen)
Isn’t there a black mirror episode about someone experiencing a terrible fate because of a malfunctioning brain implant that just got FDA approval?
