The same thing happens to me, previously in my country they did not have the option of casinos, because they were prohibited by a government that wants to have control of everything, however when one goes to another country, I have half an hour another country and the same thing happened to me as to you, I saw and entered the casinos, I saw how people moved their money, and they gambled large sums, actually I was embarrassed to bet very little with respect to them, I didn't want to be the one to make them laugh at them, and so I refrained because I really didn't think I was at their level even to be able to play, I don't know, I think I felt a little bad, maybe intimidated.
You just said the exact situation of things are going with gambling in the casino in respect to government ban, if you're to see the way sone gamblers stake bet with a whopping sum of money good enough to start a big business into gambling you will be surprised, that's why to an extent i still don't blame the government for placing a ban for some particular reasons, money embazzlers, scammers, thieves and all manner of illicit caliber of gamblers constitute a very abusive use of money in some casinos, I've seen gamblers using money to clean up their asshole, some burning it, some wasting and threading upon fiat paper currency all in the casinos, this makes government put some restrictions to an extent for some of these casinos regarding their locations.
