Food complain

Good day I bought breakfast today at kauai hatfield, breakfast bowl and the yoghurt was expired. I took it to the restaurant to be fixed and they took it. Thought they would bring my order back but they left me there without an explanation.

I waited there for more than 30 minutes without feedback and I got iritated. I love the food there but what I got today was junk, I am very disappointed in the service.
