For someone is losing their money a lot, the crowd and the noise must be very annoying. I can't imagine to play at the place, how I can focus on the gambling games with too crowded people around. Luckily I never visited or played at physical casinos (casino house) till now, so I didn't need to experience it. 

I have no intention to play at crowded casinos like that picture. I think playing at online casino sites much better. I can play at any place and can focus because no one disrupts my concentration. But it can be different with others, some people may have no problem with concentration even in a crowded place.
