I work in a dairy department in a grocery store.
Story 1: A woman was asking about the difference between cage-free and organic and "certified humane" eggs. As we are talking she says, "I'm just trying to do the best I can. I was vegan for years, until my fingernails fell off."
Story 2: A woman was asking for a specific flavor of a specific brand of yogurt for her baby. I didn't have it, but I had that same flavor as a "baby" yogurt. She looks at it and says, "Whole milk? I haven't given my baby whole milk in over a year!"
