Actually, I think shyness is always present in the first experience of the gambler (when he is a beginner) especially in the real casino because In that place there is always a crowd of people and mostly in the field of poker games.
Furthermore, the majority of people choose to gamble in online games and particularly in the field of sports (Football betting...) because there is no shyness in that and The financial value of gambling in online games is acceptable compared to the real casino where the cost is very high.
