this is a very interesting fact,
people waiting in line must be very curious about what is really in the casino, I can't imagine the euphoria that happened in the world's first casino.
Even though it was the very first casino, which may have contributed towards the enthusiasm and excitement of the whole situation, I doubt that the people did not understand the risks of gambling as gambling itself was definitely not a new concept. People just just gambled in private.
The crowd was probably just thrilled at the idea of official gambling and something new. Gambling may have not quite been legal yet, at that point.
I imagine its like when weed got legalized.
Whenever there's new thing and since governance is just on default then it would be soon legalized which is likely to happen considering on how much that they would able to benefit out then there's no doubt about
prohibition or something.It would really be just normal that people would be on line and trying out something which they arent able to experience even though you are aware with gambling risk
but speaking with new or overall experience on the first casino will really be giving out that curiosity and interest if you were there for sure.
