People often ask why, if 7-Elevens are open twenty-four hours a day, every day of the year, is it necessary for the stores to have locks on the doors. Unfortunately the answer is pretty boring, but you want the truth, right?

7-Elevens' must have locks on the doors to comply with Government Health, Safety and Fire Regulations. Basically, any place of business must meet certain criteria in order to be able to conduct business - a restaurant must be clean, for instance. I believe (though not sure - I'm not a lawyer) that in order for convenience stores to be able to operate, one of the standards set is that the doors must be able to be locked.
