I have a severe case of ichthyophobia (fear of fish), and I would flip my sh-t I bought what was supposed to be chicken and it turned out to be tuna. No, ma'am. That is not okay.
Per the USDA, Willow Tree Poultry Farm has recalled 440 pounds of “tuna salad products” after a Whole Foods employee noticed some packages labeled by the company as “buffalo style chicken salad” actually contained tuna. (Jezebel)
I imagine that person sat poking at their food going, "Is this chicken, what I have? Or is this fish?"
