What do you mean switches don't come pre-Sharpied?

My 8-Port Switch took a beating while at Summer Camp and I puchased a new one from Staples a week ago with plans on returning the old one in it’s stead.  I walk in non-schalantly and put the perfectly boxed switch on the customer service counter and then my plan hit a snag.  The service agent turned the device around and showed me where I had marked in multi-color Sharpie which ports worked and which went to what device.  Oops.  So, I did the only thing I could, I told a rediculous lie.  I looked the rep straight in the eye and said “It came like that”.
