Such a polarizing question, where's the middle aged ones? I'm sure that if you add it, they're definitely the highest number of the gambling population in my country but if it were only the two, I'd say that it's the elderly, we may see more young people gambling on the streets but they're not that many, you just see the same kid probably gambling on different places, elderly gamblers do it in casinos, they do their thing where they can get their drinks, enjoy the ambience and if they're the perverted old man kind, touch the butts of hostesses in the casino, basically sexually assaulting them, plus the elderly got more money because most of them if not all are pensioners.
Have you personally seen that kind of attitude coming from the elderly who like to spend time in casinos? They sexually assaulting the hostesses ?
Here in my country that is breaking the gambling and house etiquette in a very serious way and one could easily be thrown out the place for such things. Perhaps the culture of our countries are very different from one another, but I am still curious whether that is tolerated there or not.
Also, kind of ironic you mention the elderly can afford to gamble there because they receive money from their pension programs, because here it is completely the contrary situation, the pension is so low they can barely manage to eat, if they do not have the support of the rest of their family.
It only shows how different the situation of gamblers can be, according to where they live.
