Would that be a covenant on revenue vs a covenant on rental price? Wouldn’t that amount to the same thing. I’m not in that industry nor have I paid particular attention to it, just going by a rumor I head from a friend.

Perhaps instead of a covenant it could be more implicitly enforced by suggesting if there is a revenue drop they’ll revalue the property and force the landlord to make up the difference which could be financially ruinous for some.
