I check, ep bets, folds to me and I call getting 12+:1 with my overcard and backdoor flushdraw.

I donk, he calls
river bricks, I bet, he calls
I show, he mucks and says "ya nice call on the flop buddy"
I say nothing, but the dealer was apparently amused because he says "I've seen him call on the flop with nothing before. This aint the first time and probably won't be the last. I think he's a professional."
To which I say nothing.
To answer the op:
I don't like it but I'm not going to go out of my way to educate players on strategy or ethics at the table. It's kinda like being a kid, when one of your friends is doing something dumb and or out of line and all you can do is let them make an ass of themselves.
