Family Dollar complaint: Eating..no patience

I went into family dollar to load a cash app card..
I walked into the store and noticed the cashier in a corner watching her phone and eating..I walked over to the register she was at..it was closed..walked back around to the other side a stood there waiting for the cashier to get done eating and watching her phone.. Finally she came to the register and I asked to load a cash app card..
With no patience she said I have to have the card..I have the card..last night the cashier said I needed the bar code..so I declined.. I asked to try again ..she says its not going to work with rudeness in her voice..the customer behind me if all cards are declining..
I turned and said.. No she’s just waiting to get back to her eating a d phone..
There was a slight argument and I’m no longer back in store..which is fine..
Very dirty in keep store..very gross..
Very very rude
