Explain; had you heard a salesperson say something similar?
I had a salesperson who didn't know jack shit about anything. Someone wanted to know what cable they needed to hook up their router, or cable modem, or something. His response was, "USB or Ethernet"?
He pronounced Ethernet wrong. Also, in America, hardly anything at all (nothing at Target at least) uses USB for network data (I have heard it is used in the UK). I stepped in and corrected him. He gave me a dirty look later, and I told him that "Next time, you may feel free to give the guests the wrong information."
He quit later. I heard he works at Del Taco now.
He was in his 40's or 50's.
