Asking because it seems unusual to me, and I think those situations are really similar to what GP was referring to: "I paid to see what you had to say, but I don't like it so I'd like my money back". I can think of a lot of similar situations (movies, digital music, books, ...) where I wouldn't consider asking for a refund after I have consumed the content, whether I liked it or not.
