This is the single most misunderstood part of local search. Google weighs the distance between the searcher and your business heavily, so the map pack you see standing in your own shop is not the map pack a customer sees three miles away. Someone searching from Wellington gets a different set of results than someone on Clematis Street, even for the identical query.
So "I don't show up" often means "I don't show up where my customers are." You can't move your building, but you can widen the radius where you're eligible: genuinely local pages for each area you serve, reviews that mention those areas, and links from organizations in them. Checking your rank from a single location — your desk — will keep hiding the real picture.
