I have to agree about refund or maybe it will be better if the bet is cancelled directly when the dealer make a mistake like that. I think that will be the fairest action for both the casino and the player. I'm not pretty sure what Stake did after they watched this video, did they give a refund to the player? And I think we should put the bet amount aside because it is not the main problem here. Even if the bet amount is just few cents, there should be fair rule/term when there is a mistake from the dealer.
I think it depends on which way we look at it, we all agree it was clearly a mistake by the dealer the question is whether it was intentionally to cheat players or just a technical error/human error if we consider it to be cheating then we have to consider the bet amount because it doesn't make sense for them to risk their reputation for just $22 and also risks losing users, if it is a technical error then the dealer must get a warning from the provider because it can give rise to negative assumptions. By the way, the dealer and everything in the studio does not belong to stake.com they only rent from third parties so Stake cannot take action against the dealer however Stake may submit a complaint.
It's a good thing it was caught up and not swept under the rug.
