It doesnt say she had a receipt for the original bra. This story smells. But she will probably be successful in suing the store, unless she had more stuff with censors in her bag.
But there were certain telltale signs, the most obvious of which included no bag & no receipt.
We had a black manager at my store, great stand-up guy and I remember one encounter in particular because the woman (I won't say what color she was) approached me to demand a refund. I called my manager over and he asked a few pointed questions which ended with her getting huffy and exclaiming "I don't appreciate being called a liar!" He calmly replied "And I don't appreciate being lied to" before escorting her to a back room to explain her options to avoid arrest and a police record.
“It doesnt say she had a receipt for the original bra.”
She could have stole one and bought one. Then brought back the stolen one to have the sensor removed.
