locks on 7-11 stores which are open 24 hours a day, 365 days a year Discuss this oxymoron in the comments below. Bob wtf? Bob wtf? Abc necessary to secure store after a robbery attempt! Asfasdfahgasg i dont get it Iluvoxymorons OH I GET IT! 7-11 stores are always open, 24-7. It never closes down at night, cause there’s a night shift. What’s the use of a lock? A lock prevents robbery to take place when a store is closed for the night. But 7-11 never closes! Get it now???
