I was at Walmart getting a tablet cover for mom when someone approached me:
customer: "do the TVs turn on?"
me: "I assume so. They are kind of useless if they don't."
customer: "you don't work here do you?"
me: "no."
customer: "I was wondering why you weren't answering the phone." (it was ringing at the electronics department desk)
I was standing there in a burgundy tee shirt, jeans and black ranger vest. Not even close to the Walmart uniform.
