Family Dollar

So I walked in with a return a little after opening she said she could not do the return until the boss was in so I showed her the back of the item saying not 100% satisfied return to any family dollar for a return then she was able to do the return then I started to shop and was followed thur the entire store by her so I decided to just leave as I left she ran out and took my plate number down so I called her and asked why she pretty much told me it was because she thought I looked like I would steal something and that if something did come missing it would be blamed on me
