I don't really mess with casinos.
I will play lotto if it gets big in the hundred millions.
Only time I bet on fights is if it's a big money fight and I find fools willing to go against the favorite. Example, the Mayweather - Pacquio fight I won like $2K-$3K willing to bet anyone who would go against Mayweather and a lot of fools actually bet in favor of Pacquio.
But, I lost like $1.5K - $2K on the Macgregor vs Jose Aldo fight

Aldo hadn't lost in like 10 years and that fool got layed out. Man that day sucked donkey balls I was heated, but payed out everyone except one dude
Story of dude I didn't pay:
Got into it with this fool who bet me for the May-Pac fight and lost and he didn't pay up and then he won against me on the Macgregor-Aldo fight and came asking me for his money. Dude thought he was going to collect after he didn't pay me I was laughing and then he seemed to start getting serious and then trying to a middle ground. Talking about take what I won from the May-Pac fight and give him what's owed to him from the Conor-Aldo fight. I won $200 from the May-Pac fight from him, but him and like two other people were the only ones I didn't collect the money from (that was the rule if you were betting me you had to have cash in hand or whatever and I hold onto it until after the results) the two other dudes payed up, but he didn't and I wasn't really stressing him for it. Conor-Aldo fight he wants to bet again and I do it thinking I was going to win for sure and again not expecting him to pay if I do so I said double or nothing and he says nah let's do $500 I said okay whatever. He wasn't going to pay if he won just like the May and Pac fight so I wasn't planning to pay him regardless and then when Aldo lost I told him straight up I'm not paying and dude got heated

what's worst is I payed everyone else off that I lost to except him and he was livid
Straight deaded that bum B and dude was trying to flex and I stood up and was prepared to pummel him and I think one of his homies told him to just let it go. He then came back and tried to collect $300 instead of the $500 to subtract the $200 he lost against me in the May-Pac fight. I still said no I'm not paying you **** and he was drinking and I was ready and so was some other cats there and he kept walking back and forth barking, but never did anything and I saw him again after that night and I was dolo and he just looked at me and kept it moving.
