We can buy glasses at an optician's shop. We can buy jewels at a jewel's store. Do we have to use shop or store in this case? optician's shop/store, jeweler's shop/store..... Are both OK?
We often don't use "shop" or "store" with these words. We buy jewels at a jeweler's or a jewelry store. We buy glasses at the optician's. We buy food at a grocery store or at the grocer's.
