Commercial language is interesting. For example, “store” as a term is short for storehouse, a place where you stored things. We now think of “store” as a place where you buy things, though there are commercial enterprises that specifically allow you to store things, distinguished from stores by calling them “self store.”
Convenience stores are not places where you conveniently store things but, rather, shops that are conveniently placed to sell us something.
Now, with the word “store” and “convenience” in mind, consider this sign, which claims that, for the convenience of the customer, tires are sold in the Tire Center:
But another possibility exists beyond convenience. It is possible, for example, that tires were previously sold in lingerie, or bundled with avocados. It is possible that an attempt was made to sell them online, only to be abandoned after customers complained about the lengthy download time.
Or — it is just possible that it is for the convenience of the store to sell tires in the Tire Center, and not with baked goods or potted plants.
