I feel the player's pain losing 2k to gambling in just one seating is an experience no one will love to have, but then it happens sometimes and at that, the ops need to move on, I experience some losses last week but not up to that amount mentioned by the ops mind was my campaign payment for the last week.
$2k is a small amount for huge spender. It is become a pain if the person who gambled that $2k got hooked and gambled the amount he can't afford to lose. I also agree that the guy shoule just move on and let go of the feeling of regret so that he can enjoy his next gambling session. Restarting a fresh is way better than holding on the remorse due to the uncontrolled losses.
I felt bad to have used the entire amount to stake on a sports bet but when I remember the multiple times I have won on stake, it will keep me motivated not to give up but to apply caution next time.
I think it is normal to feel bad sometimes but what is good is that we can learn from our wrong moves and apply what we had learned in our future gambling sessions.
