This guy is the perfect example of why you shouldn't stay at work past regular business hours. If your company/building can't afford to have security guards 24/7, they don't need people in the building. If they can't afford security guards, they can't afford overtime.
Last year, a man was stuck in an elevator for THREE DAYS. He made contact with security via the phone, but they couldn't understand what he was saying (didn't speak English). So, NATURALLY, they couldn't be bothered to check it out. One person, calling from an elevator for a whole day should have raised some questions.
Try not to let your life depend on stupid people. The odds are bad because there are so many of them.
