That matches my personal experience, for sure. I have been to a casino exactly once (aside from playing nickel slots at LAS a couple times just to kill some time). As I recall, it was indeed $50 that I lost. Very quickly, too. I felt terrible. Stupid for even playing a game I knew was stacked against me.

Never been back. The only gambling I do now is buying a $2 powerball ticket every time the jackpot goes above $1B. The momentary fantasy is worth the two bucks.
