Have you ever been in a situation where you took a big loss. clearly because of your own mistake but instead of owning it, you ended up blaming the casino? Maybe made some excuses just to avoid feeling stupid?
Of course, that's why those who pass the buck do it. They do it so they don't appear or feel stupid before others. I think of when gamblers blame their bad games on casinos the same way when I see bad artisans blame their tools for their poor showing when they do shoddy jobs. Casinos may have an edge on gamblers but we should also accept responsibility for our gambling habit and outing whenever we goof. Shifting blame won't help us spot the mistake in choices of bet we make, accepting responsibility for our mistake does as it affords us that opportunity to have a reassessment of our bets.
I don't blame anyone when I lose. I know my engagements are solely my responsibility.
