Okay look, it's a common mistake! You might be thinking how so, but when I was younger like around 13 I ate about 3-4 of what I thought were cookies but turns out they were dog treats. You might be thinking to yourself," how didn't you know?" Well, I was paying attention and I thought my Mom bought some new cookies. So yeah it's more common than you think but for 20 years?
A woman on Reddit says she was talking to her dad about gas prices recently, and that led to him telling her about these amazing "biscuits" he picks up at the local gas station every time he goes. He's been grabbing them for about 20 years. She was curious, so he brought her a pack. She looked it over, and told him that they were clearly DOG TREATS. He was shocked, and said he doesn't know if he'll keep eating them, because they "don't taste the same now that he knows."
