I think when someone tends to gamble more frequently could also be a cue too. Because how often a person gamblers should have a limit, maybe once a day, if you really enjoy gambling that much or if they have free time more often to gamble, but when a person gamblers more often or discovers he spends more time in gambling to the extent that it even interrupts or prevents him from doing other important things, then we can consider that to be a red flag or a cue that the person shoulf take a break for a while, because proceeding further with such attitude could lead to addiction.
