I can tell you that I've seen them change the grease myself while eating there. The onion rings were probably just overcooked.
I was employed at the Whataburger on Sycamore School Road in South Fort Worth for five years. We changed the grease in the fryers every other day. That's the way it should be done but not all stores do the same.
Never gade a issue tgere
They dont change at that location. I dont buy onion rings there anymore either. But burger and fries good.
