If the 7-11 is open 24 hours a day, 365 days a year, why does it have locks on the door?
economist in me:-
It does not make sense to buy or produce special doors without locks just for 7-Eleven.
It is more economical to install standard doors with locks.
the business thinking in me:-
Not all 7-Elevens are 24hours, especially those in foreign countries.
In singapore, some 7-Eleven in hospitals are not 24hours.
the operator in me:-
in case of emergency, can lock and go.
There are actually many various reasons why 24/7 shops have locks.
One of them from WikiAnswers.
Doors are made that way. They are are manufactured with locks. You can't buy an exterior door that doesn't come with a lock.
