What back up individual stores have is not universal and is based on a given minimum turn over. Which will decide which stores get what it will mostly be lager stores and even then the back is limited. Even then its it's mostly to keep store ticking over it wont be enough to keep it open as normal. Smaller store will almost certain to not have any form of back up and will just close. Same sort of thing happens at the other end of the scale. A given leakage figure has to be met before a store gets security or if they get trolleys fitted with security clamps.
