For example, suppose you encounter a gambler who has wagered $200 at the table and is currently winning $6k. Would you express to them, "Hey, you're up $6k, and you initially entered this table with $200. Walk away, Take your winnings, go!" or will you say, "It is very admirable to know when to stop"?
What will you say within your limits to encourage responsible gambling?
The worker will not say anything. The worker do not have to say anything. Casinos will have rules, their works should not violate any of the rules. What I have noticed is that no worker will encourage you to stop playing, they will not also encourage you to continue playing. It is you that will tell yourself what that is right.
I agree with your statement.
This is actually a difficult choice for the staff if they truly want to encourage responsible gambling without infringing and violating their TOS. For the safest route, they can just ignore and not say anything to the players. If they make one (1) mistake, then they can potentially lose their jobs, therefore impeding the opportunity for their livelihood.
Again, it is somehow a difficult line to draw especially if you are an advocate of responsible gambling. But if you are a staff working at such casino and you also want to spread the message of responsible gambling, then it is better to quit your job (to avoid any conflict of interest) and be an advocate for such.
