The issue is: how do you define "fair proportion"? And that is when you are in a situation where you've got a tenant who is highly stressed, has no money, and is in a difficult situation, and every week means that they will be losing more money. Therefore, you're in a situation where this clause actually is unlikely to present much of an option, because in many cases a lot of these businesses have gone or will go to the wall, which we're seeing in increasing numbers.
