Do you actually put olives on top of your sandwiches?
When you look at a cartoon illustration of a sandwich, you will usually an olive or other similar topping on top of the sandwich. Have you actually put olives on top of your sandwiches? If so, why?
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.
