I believe the sandwiches you are referring to are called club sandwiches which are held together by a cocktail stick (a big toothpick basically). I guess the olives are stuck on them for decoration and to be eaten. I google image searched “club sandwich olives” and it seems fairly common.

Now, I don’t make sandwiches like those, so to answer your question, no, I don’t.

I'm imagining OP as someone who has never made a sandwich and dreams about doing it one day. Until then all they can do is look at pictures of sandwiches, imagining what they might do.
