I got to thinking about this, and since those stores are franchises, I doubt every one would be doing it.
Would take a wealthy owner to pay all the expenses for a day with no income for that day.
I had a neighbor in Delaware that owned Dunkin Donuts stores.
He made vary little money when he started with the first one.
I think he has 5 now.
The corporation pressures owners to own 5 so they make a decent living and would be less likely to go out of business.
If a store shuts down, the corporation loses money, as the owners have to buy everything from them.
Every 10 years they have to do a facelift on the outside of the stores at owners expense.
I suspect other franchises are like that an not big moneymakers.
