Well, I must be the rarest example in this thread, but I have to say that nothing has really driven me crazy at any online casino I have ever played. I am not really keen to gambling online, but I am not a newbie either, and it may be because I have always chosen relatively well reputed casinos and bookmakers, with great UIs and prompt response from support when I had any problem.
OK, to be honest, it drives me crazy when I lose my bets, and it happens to me most of the time; but this is something I can't blame casinos for.
You are probably a very calm, confident person, and that's a good thing. It is from people like you that professional players turn out, for whom, with any outcome of the game on the face, it is generally impossible to understand the emotions of such a player. We can say you are lucky and your parents have invested in your character such useful properties for life.
But, of course, any player has annoyance from losing. It's just that everyone behaves differently. The losing player can even break the computer, or he can smile and forget about the loss. But if, of course, the player breaks the computer, this is already the fact that he has "lost his mind."
And you are right - no matter what casino he played in, here he should only blame himself and not the casino.
