I'm not a genius but far from stupid

I recently went to a Dollar General that's kind of out of my way but I wanted to try a different location just to see if I might get lucky and find some new Hot Wheels. I ask a sales lady if any new Hot Wheels had arrived. She seemed excited to tell me that indeed they had a box in the back. She brings out a box that had already been open not only the top but the bottom also. And then the flaps folded over. I said that it appears someone had already opened the box and picked out what they wanted. She said to me with a straight face that they open all the boxes before putting them out! Anyway I went thru the box anyway and I could tell 3 or 4 were missing. What a BS sales lady. Never going back there sgain.
