I feel you both there. I have my own superstitious beliefs too and I do respect those who do the same thing in front of me because who knows if it could really work and that boosts the confidence of that gambler on his bets which I think is a positive vibe for everyone around him.
I think superstitious beliefs have been part of the gambling world for a long time. When I was young I heard from the old ones who were playing cards that the man with a bit of bad luck should wash his hands because it has a bad odor and that is why he is getting a bad card hand too. It was kind of funny but I don't see them laughing and I think they seriously believe it.
Having clean hands means having a clean hand of cards too.
It's kind of weird but maybe it did work before and the belief was stuck and still known to some gamblers, especially the old ones.
You are right. We can accept their superstitious beliefs because they have been used to doing them for a long time and cannot be eliminated no matter what. They believe in these superstitious things because they have seen what happened to people who have used them in the past or they have received advice from older adults in the past. After all, gambling is one of the oldest cultures that has existed. Hence, it is possible that superstitious beliefs already exist, especially in countries in Asia which are very steeped in culture.
But what you said about washing your hands before playing cards makes sense because with clean hands, who knows, our luck will come and give us victory. Well, there are still a lot of superstitions out there, especially those who still practice them.
Some gamblers engage in some form of rituals to increase their chances of winning, this could be done at home before coming to the casino or some do it in the game house or casino, they may do it before or after staking, whichever it's just for the purpose of tilting the chances in their favour, some times they happen to be lucky and the other times they are not.
This said rituals been carried out by the gamblers can be considered fine if it's not affecting others but if it does then it should be regulated especially the once who do in the casino, the casino management could place an order in the casinos to stop or regulate this gamblers who carry out such activities especially if its making other players uncomfortable.
But then if it's not harmful and if it doesn't cause anybody discomfort they should be allowed to do their thing as it may be fun to others and create another atmosphere.
Yes, it all depends on luck because such rituals cannot guarantee they win even though they are sure they can win using that ritual. We can't blame them because they've been using it longer than we thought and as long as it doesn't disturb other visitors, it's fine. But if it becomes disturbing, we can report it to casino security. And it depends on them because if they don't want to be advised, the casino has the right to prohibit them from gambling at the casino and they have to look for another casino that can accept them.
