Burger King review: Store closing early

The last 4 times I've gone to the Burger King drive through around 8:30 pm they have said their system is down. I can see them playing and laughing inside. Now they have started blocking the drive through off every night. I drop my wife off next door at Kroger every night and I'd like to be able to get her a burger before work. I don't believe the system is down every night
