I heard a lot of bad stories from a girl I know who works at a physical casino dealing cards. So I'm not even sure I'd like to visit a small casino. All my words are about casinos in a small town, not in the capital.
So I'm not sure that it's like she said everywhere, but she said that losing players often yell at her. She didn't talk about the odds, I think they're the same everywhere, but most likely I don't think you should expect honesty in the odds of winning in small town casinos. I can't prove it, but I have a bad feeling about it.
