My daughter called me at work to say I received a call from "Josh" at the bank regarding my account. So, I called mybank and the operator asked me what Josh`s last name was and I explained that he hadn`t left his last name.When she asked for his department, I said that I didn`t know."There are 1500 employees in this building, ma`am," she told me rather sharply.So I asked her for her name."Danielle," she said."And your last name?" I asked."Sorry," she replied, "we`re not allowed to give last names."
