This is where online gambling steps up. I don't know how crowded casinos are but I saw in some of the movies with a scene in a casino and it is crowded. Now I know that it is really a crowded place

.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?
If you are a new in casinos and you are not adopt with the environment, you will feel more stressed especially with that number of noisy people around you. I'm not a gambler addict but if that is how casinos are in my place, I will not go because I don't want to go to a place with man people and I'd rather gamble online than going to a crowded casino Will you play on a crowded casinos? or just play online?
.Playing in a crowded gambling casino is very irritating and you can't gamble there comfortably. Also if the place is crowded, probably there are people who have bad intentions and make a crime like stealing money and wallet. They should limit their customers to get inside the casino for a more comfortable and peaceful gambling, the noise there is for sure distracting and people will be less patient.
In terms of online gambling, there is also a probability that the platform will be crowded that results into lagging, poor visual design, clutter and other website problems. Online gambling should be also monitored by the regulator or the maker so that people who gamble online will also feel comfort and tranquil gambling experience.
I probably not play in a gambling casino which will make me more stressful, I want a gambling casino where peace and silence is present.
