Bad attitude from the owner

We drove for about 10kms to buy 3 pizzas from Pizza Perfect in Blu Valley Mall. We waited for 10 minutes for them. While waiting the lady who came after us surprisingly got her order before us. I approached the owner what was going on. She gave me an attitude and told me to ask the guy who was preparing the pizza why he did two pizzas instead of three. I told her that she is the one who is supposed to apologise on behalf of her staff not me to ask the guy behind.. She started yelling at me saying she's not going to apologise the guy should apologise. I said as a manager she has to apologise on behalf of her staff, instead she game me a dirty look and walked away. Leaving me standing there as if I was there to get the pizzas for free. We had to wait for another 10 minutes to receive the third pizza... Is that how she runs her business... Mind you it was not my first time buying pizzas from that shop and the previous services were good without her... I trust it was my last time buying from them..... I'm so disappointed with her rude attitude. She doesn't know how to treat her customer.
