At the risk of potentially doxxing myself, I happen to know the owner.

The location change is because they own the current location in Headingley, which as an operating expense is a great deal less expensive than leasing at the former location in the city. Headingley has and is expanding (rapidly) which means more potential consumers, it is located closer proximity to farmers, and there are already a number of businesses in that area so it made sense to move there.

Not all businesses will succeed, in fact with the way the overall system we have is setup, most won't. Hence why we have so much consolidation in businesses, oligopolies and monopolies. Big box stores instead of numerous (more) mom&pop shops. A lack of competition, by design. Superstore can afford to sell a "English cucumber for $2.99" because it can and does make its profit elsewhere.

He would gladly have paid the employees more if the business could afford to do so. I know the owner well enough to say that he is not landing the fault of the closure on the rise of minimum wages. He's blaming a simple fact of business, rising costs and dropping revenue. Only so much can be done for either. Unfortunately consumers won't accept higher prices, suppliers won't bring their prices down, and by law he is forced to increase wages. The business cannot sustain, and thus it closes.

Try to see the forest for the trees people.
