When one buys new dishes from a store (e.g. cutlery, plates, bowls), is there any concern that they are not as "new" as they are claimed to be?
For example, someone buys some cutlery and plates, cooks some bacon and subsequently uses the cutlery and plates to eat that piping-hot bacon. Then he decides he doesn't like the cutlery and plates, cleans them really well, repackages them so they look unused and returns them to the store. The store judges that the plates are in "brand new" condition and restocks them as new items, with no indication of being "open box". If a Jew subsequently purchases those plates or that cutlery, why should he not have to kasher it?
- Stores never actually do this, or at least reputable stores. Once it's sold and returned, it's immediately "open box" and never resold without this being indicated to the next buyer. (I don't know enough about the retail industry to know if this is the case).
- There's some sort of rarity thing going on here since the scenario is very unlikely.
- Everybody actually does kasher all the new dishes they buy and no one ever bothered telling me. (Seems unlikely as some things are less kasherable than others -- see opinions about Kahering china).
(Related to Hagala for a new pot, however different in that the concern there is the manufacturing process for metal cooking dishes, whereas this question is about when "new" might mean "just barely used".)
