are employees required to provide their full name and/or job title when asked by a customer

I don't know of any countermen based job that does. And most cases job title is on the name tags

Name tags give this information And rude is a 2 way street Give what you get ....smile and try being open to niceness

This is not a job it's the name of the store a store up and down the East Coast. If you are looking to stock up the shelves 🤠 this is a job for you
