Seeing the words: 'Access denied' has to be one of the most infuriating encounters. I mean, right up there with discovering you have a flat tire while dashing out the door on your way to work. Funnily enough, this tends to happen when you're in a mad rush or trying to meet a tight deadline. Being unable to obtain what virtually belongs to you seems a bit unfair. Even if it's because of something as trivial as forgetting your passcode, having an expired key card or perhaps not having the key at all. Yet isn't it amazing how many people think being available means they should be accessible too?
