Booking agents: do you feel any responsibility to venues?

I'm a buyer and I just saw an ad pop up in my feeds for an artist I broke in the market a few years ago to play a different venue in town. I didn't even get the chance to make an offer. If there was any honor in the business, I would have right of first refusal. Now, they may have gotten too big and I can't make the money work and I don't end up getting the show. But doesn't the agent at least owe me something? Am I living in a fantasy world?
