Before I could give him my email address, a very agitated chubby white male with a red badge wedged himself between us and demanded that I show him my badge and tell him who my manager was. He told me the yellow-badged workers were “extremely confidential people” doing “extremely confidential work”, and I was standing in an “extremely confidential area”. He then reprimanded the yellow-badge worker for talking to me. I then found out the chubby white man knew what I was doing because the first girl I had spoken to had followed the instructions on the back of her yellow badge – which is to call a certain manager if anyone asks about the work of the yellow badge class.
