Because they want to feel that big experience again, they don't realized how much money they are losing now.
We have enough with the experiences and it's time to spend money wisely. When you are not winning anymore, stop for the day.
Some gamblers just don't have the acceptance on a day that they lose. I can argue with it, I experienced the same feeling of losing in the beginning of the day and you'll just start drifting in a losing streak on thinking that the tables would turn on your side, not realizing how big the table is.
You don't have to prove anything with what you have because that's just going to cost you a lot of mone when you are going that far.
Acceptance that it is not working on you will make you stop.
But rarely, or almost not, I can manage to bounce back or break even at the end of the day. However, that doesn't mean that I got lucky, continuous playing would consume so much time to anyone whether you are playing on casino or online casino, I realized how much time I have lost trying to get a small win or break even after a day of losing. It is not worth of your time, learn to accept defeat and look away to spend your time and money wisely.
