You can return food. They don’t like it and if you do it too much they’ll stop allowing you to return food.

But I’ve definitely returned food that I didn’t like.

Once they even let the guy in front of me return an empty container. He said he had to eat the whole thing to decide he didn’t like it.

We have returned food. Sometimes it has been stuff which we didn't like the taste of or produce which has gone bad very quickly. We don't do it often but it happens. Never had any issues in returning it.

You can 100% return food. I've returned fruit before that was spoiled and some Kirkland brand k-cups which were the worst thing I've ever bought from there.

I returned a fruitcake to Costco.

I was so disappointed that Costco had sold me something so subpar I returned it. I don’t know what they were thinking.
