Bad attitude and hygiene

I went to Debonairs Pizza at waterfall Mall on the 12th of March. The lady who was helping me and my little sister gave us an attitude. Firstly before we placed an order she was busy picking her nose infront of us. Then we waited for our order fine, after then the guy who was busy with our order then said to the lady that our order was ready she ignored him and when I asked her she yelled at me telling me she's busy.

Firstly hygiene doesn't play a role in that store and the lady had an attitude for days. She was even being rude like that infront of her manager. Even when I told her that I'll report her on hello Peter she said she doesn't care.

I don't see myself going back to that store ever, it was my first and last time.
