You guys do know that there are other factors that could go into justifying/keeping a franchise store open.
For instance, some franchise uses a minimum profit scale. If the store can not meet or surpass the minimum profit range, then it is considered a burden despite the fact that it is the only store in a city or that it is still making a profit.
Funny thing, it is not uncommon for HQ to recalculate the minimum profit and justify reopening a store a few years later.
Know this, it is possible that the top 10% percent of profittable stores also are the reason why the minimum profit is at the level it is. A very bad use of financial stats that can be utilized for other reasons.
