I think she’s aware there are people waiting for her to fail& close shop.
She seems to want to prove herself and prove her doubters wrong
What gives you the impression she’s aware that seemingly one person is waiting for her to fail? And what has proving doubters wrong and not closing shop got to do with consistently delivering orders late?
Because the person seems to follow her movements - see posts about all her old shops
& by the looks of her facebook - she has had words with the person who continuously criticises her to.
They have been spreading the faults made from her past - she may feel she has to use this clean slate to clear her name.
Just a theory. I’m just adding my opinion/ assumption
