People are bored and don't have any other hobbies to do so casino it is.
Kid you not, before the pandemic and where I'm from, the only old people that pull slots machines are older people whom have the prior experiences with casino and gaming throughout their lives. During the pandemic, we are talking about your OG mamma and papa folks who don't even speak english and pulling slots was their first year.
And they be winning
Like when you acquired a new hobby, you tend to do it again and with casino business, you then become hooked and a junkie, like me.
