People used to always appraoch me in stores as if I was a clerk and could help them.Didn't matter what I was wearing. I used to work in construction, and my clothes were covered in silicone, I looked like a painter & someone still approached me as if I worked there! Once she looked at my clothes she was kind of embarassed when she realized her mistake, poor thing. I told her it happens to me all the time. I never got nurse or teacher though!
