At 1:30 in the morning you are driving down Walton Road when you pass the 7-11. You decide to stop in and treat yourself to a nice big slurpee. As you pull in the parking lot you notice that the sign says, "We're open 24 hr's, 7 days a week, 365 days a year." However, when you reach the door you notice that they have locks on the doors and you think to yourself, why do convenient stores have locks on their doors if they're going to be open 24 hours a day, 7 days a week, and 365 days a year? If they're never going to close then they have no need for locks on the doors. This will only cause an inconvenience for employees and customers.
The idea of adding locks onto the doors is only going to cost the store more money. Also, it would give the managers one extra key on their already big key chain that they really have no use for. Since they are open every second of the year, they never need to lock the doors between shifts. When one person's shift is over then the next person will come in and take over. It's not like most stores where at night when the store closes they lock the doors and go home. Then, in the morning whoever is going to be opening comes in and unlocks the store and gets it ready for the first customers of the day. This situation would never happen at a store that is open all the time because there always has to be someone working.
On a rare occasion, the store might need to the lock the doors if someone outside is causing trouble. However, if they locked the doors and wouldn't let any customers in they would be lying saying that they're open 24 hours a day, 7 days a week, and 365 days a year. Doing this would cause the store to lose money because no one could then get into the store.
By adding locks onto the doors would also make people think that sometimes they do close, like on holidays. On almost all national holidays like...
