If it's your place, your pond, your fish, I think it's your rules, whatever these might be.
I absolutely agree. I don't think the average person realizes how much effort goes in to the ponds we have. It's a labor of love, and we enjoy sharing, but...
The few instances I've had were guests assuming a single invitation meant they could come back and bring family/friends. I never heard from them again once they couldn't fish under their terms, and that was fine by me.
To me it's like sharing a hunt. You pick up your shells, cans, trash, and respect the property rules. A pond is no different.
