Is very simple, Subway need to ask her self how many new restaurant are open the last two year versus how many store are close the same last two year. Now every franchisee look to get way out. The value of the Subway store worth notting.

I like to work in my restaurant

The franchisors don't care about the profit of the franchisees. All move they do, is about they profiability, not the profiability of the franchisee.

the profiability of the franchisee... stopping to increase the hours of the store, stopping to insert new product no tested like porchetta. And the price of remodeling is to expensif. The profit vs the remodeling give any other way to close the store.
