Unfortunatelly, this is the kind of dangerous situation an addicted gambler faces, because he can't control his urges for playing or chasing losses.
Uhmm, I think you both have realized that the last money or cash the OP was talking about was just $1 and yeah it was supposed to be for his transportation back home, but you guys may have overlooked the last statement, he said he still have enough money on his account to use it for his transportation if in case he lost the $1.
I think you are guys are just overreacting over the $10 whom the OP have lost and then used his last money which was $1 to go for an extra mile. I'm pretty sure It wasn't an act of addiction, he was just trying for his luck.
I might say he's addicted if he have mentioned that he has plan on spending more on gambling if he'd lose that last $1, because again, he had mentioned that he still have more money in his account that just the $11 in total as his capital in gambling.
