If I go to a store and the cashier asks "有會買嗎?" what does that mean? For example, if a cashier rings me up and says "這樣一共是五百元, 有會買嗎?" What does the "有會買嗎" mean and how would I respond? Thank you.
Are you sure it's not "有會員嗎"(員 vs. 買)? It certainly sounds like it, the cashier is asking if you have a membership at the store.
