I would say the best thing to do would be not to play in the casinos, so you won't have any problems with them.
However, as nigeljc59 said, the decision is always yours. I certainly wouldn't play in casinos that aren't licensed, that have a low safety index, or that a lot of players have had problems with. On that topic, I thought I'd give you our pretty well written guide on how to choose a casino. You'll find a lot of useful information here that might help you in your decision making.
Also, if you look at our site you can see user reviews of players or complaints, which can also give you some insight into what kind of things players are dealing with in casinos and what is the most common issues. I would always keep an overview to minimize the occurrence of unpleasant situations.
However, sometimes you can do all of these things and still run into a casino where you will have trouble. Nothing can be guaranteed and you can't say that this is the perfect casino where nothing will ever go wrong. 🙂
