Unhygienic woolworths staff

Checking out the cashier has a cold. Sniffing back her mucus and then rubbing her nose and continuing to pack my foodstuff. Thats really hygienic. When point it out. She is sorry. Management is sorry. But she continues. At what stage do they realise that sorry isn't hygienic or that my food isn't contaminated. Really a poor showing for woolworths
