(ABC News) -- Restaurant health guidelines may vary by region, but there are certain violations that get Internet critics all revved up. After a photo of a barefoot worker preparing food in a Taco John's kitchen in Charles City, Iowa, made its rounds online, the woman was fired for violating company policy and state health regulations, according to the Des Moines Register.
A customer complained, saying an employee "was preparing food in her bare feet and was wearing a tank top and was sweating badly and handling food," the Des Moines Register reported.
In response to the photo that was posted on Taco John's Facebook page, the company said on Facebook, "Taco John's takes health requirements very seriously. We've followed up with both the restaurant and the original poster of this image to resolve the situation."
