I have viewed and watched some videos on youtube concerning big casinos, I can see there that japan has actually have one, and there are higher than two thousand employees, that's how big that casino is, and one thing I've noticed is that, no matter how big they are, there is still order because of the proper monitoring and control of their employees. So, people are already falling in line one hour before their casino opens and guess what, the gamblers do actually have their own stations to play with and they can even have a break, reserving their machines for them.
For me, in crowded casinos like these, I definitely play in casinos like what japan has, the only problem I can see is the noise from the machine but I can take that to consideration.
Japanese people are indeed great and well disciplined, not only in casinos but, also in the way they interact and do actions in their daily lives: people are obedient both on complex and simple rules such as falling in line and giving way for elderly. Even with such big casino, it still shows how disciplined they are because, in the usual scenarios it would be a total chaos.
