I don't have much time to gamble, and I'm thinking if those gamblers is really there to have fun or to earn money after all?
I can't just imagine to have fun at the huge crowd, and so many people around you at the poker table.
Is it worth to play? or the crowd and the noise around you will just add to your stress?
Will you play on a crowded casinos? or just play online?
(VIP's might have the separate room and a more solemn room, I don't know but let's talk about the general here.

)
Popular casinos are like this, and people who frequent casinos expect it to be like this, especially in Macau, when it comes to playing, gamblers can play at this kind of environment, it's not a chess match where you need a lot of concentration, they can play and in fact love to be in a casinos with many players, you have seen that in many movies where there are casino scenes.
Macau as Gambling Haven now?for sure its hard to find Casino with low volume of players specially in weekends or holidays .
but playing with that huge crown is really disturbing,there might be Robbers or pick pockets,also there are destruction from our concentration while playing.
so better play only with small amount to check our Luck ,and if its there?then continue playing but if you have no luck that day better go home and play via Online so the more silence is the more you can focus
