Goodwill Industries complaint: Store manager abusive and rude

The store manager or cashier refuse to provide me her name. To make a report about her bad attitude and her abusive attitude toward customers. I ask this lady at the store for restroom key as always do in the store.
She ask me to wait at the door that someone will help me soon after 10 minutes waiting I went back to register and ask her for how long I have to wait because they were busy and I could better leave since I live in Sunnyvale 5 minutes from the store. And she told me I told you wait we are busy and you have to wait. I told her she was being abusive and she told me. You see how busy we are. And I told her I just need the restroom. She stared walking away like ignoring me turn back and she your life is so miserable that you have to make the life of others miserable. ????? I tough this lady is so unhappy with her job and not enough with that she told me she will call the authorities over and she ask me to leave. I said call them all I need is to use restroom is that a crime. She told me leave leave now. I am not sure what her problem was or the reason to be so bitter and unhappy with her job. She walk to the sorting area and spoke with a young latino man sorting ithem in the employee area and stared laying about what happening and I explain him I just want use the restroom that I have a emergency and that’s why I need use the restroom. She told me you can ask the employee over there to open the door for you. When I done I went back and ask him about her name to make a proper report and he told me I can’t give you her name. Why they are hiding their identity. That is why I think she is abusing of her power given by Good Will. I guess she is the store manager or the cashier. And I will feel not welcome as customer if she stay there. My en voice pay number is 0672470066

She was wearing a black loose shirt and has a long black hair, is about 5.7 or 5.6 tall and wight around 250 pound.

The employee in the sorting area is a young man 5.9 with a green shirt and jeans. They both deny to provide their name. I suspect because they know what they are doing is inappropriate.
