He is known for being dishonest and you give him cash...???
Sorry dude... in my world it's dough for dough...no buds in my hand, no cash in your hand...
100% your fault...
I have lost WAY more than that, know what I learned???
ONLY INTERACT WITH PEOPLE THAT ARE TRUSTWORTHY !!!!!
MOTHERFUCKERS ARE ONLY GOOD FOR ONE THING, FUCKING YOU OVER!!!!
STAY AWAY FROM THEM...
And though a good punch in the face will feel good and righteous, violence will only bring more violence... shooting a motherfucker and going to jail for it will only ruin your life... his was already ruined anyway...
Let it go and get smarter....
and dude, like I said... I have been taken BIG before... I wish it was 50 DOLLARS!!!! but if you introduce one spec of violence in to the drug underworld... it will come pouring down your head 10 fold....
Learn your lesson, walk away with EVERYTHING IN YOUR LIFE but the 50...
You will sleep better at night...
Now wouldn't it suck if he had a flat, his cell fell in the gutter and you are just assuming he ripped you off?
