I only play at online casinos, I generally don't really like the atmosphere at real casinos, at least not the ones in my country.
Most of the casinos over here are either kinda sketchy or look like they're only for rich people.
With online gambling, especially on provably fair sites, you know what the odds of winning are and you know that you're not being cheated.
I have my doubts about that in real casinos.
I would tend to agree with this, but then I have limited experience having only visited land-based ones that are probably geared towards tourists more than gamblers. I'll say this about real casinos - the small ones with a local crowd tend to be a bit run down, with very small jackpots and very small crowds, more elderly people than young ones. But I can still enjoy them as I'm not myself what you'd call a serious gambler.
The larger ones I've been to, tourist locations at island resorts. A little glitzier, but a lot of offshore workers looking to spend some weekly earnings at tables. These tend to be cruder, louder, and generally bully the others at the same table (or even the dealer). Alcohol influence perhaps part of the play here. So quite a bit of sketchiness as you say, like I've seen weak dealers fall for the tricks of some of these guys, who place bets late, or cancel hands (very annoying if you're at the same table).
The nicest ones I've experienced are at London. Very experienced dealers and pit bosses, a not-so-strict dress code and decent high roller tables. The company is pleasant, the atmosphere very well maintained and you generally can watch the rich people play, they're not TOO brash.
But yes, you can't beat the candour and friendliness of online gambling communities. Nor the provably fair of crypto casinos (that's a HUGE advantage). Just sometimes, the beggars and the whiners. They'd never dare to mess around like that in real casinos with bouncers watching!
I think you have visited an expensive casino that’s why you are saying that there are a lot of people there except gamblers. I also want to tell you that people living at a specific place where the casinos are built, usually go to these casinos, not the tourists. Why would tourists go to the casino? There is no place left for the tourists to visit except these casinos. I didn’t have heard from anyone that tourists go to casinos, if they do go, it’s a funky thing.
