> Also unacceptable is requiring customers to do the job of an employee. A grocery store is a store that takes money in exchange for groceries, not a store that takes money in exchange for poking buttons nor a store that takes money in exchange for putting things into bags. There's nothing inherently "job of an employee" about any button poking or bagging peripheral to trading payment for goods.
