I don't really gamble much but I did get hustled by this road player.
He comes up saying that he is local and shoots a bit, wants to use my cue, trys to call bar rules on me(oh hey you didnt call that carom even though I called ball+pocket), misses "easy" shots with a dead-straight stroke, and generally gives me this "really bad actor" vibe.
Anyway, after shooting a couple games and obviously laying it on thick, I have to go and he reveals that he is better than he was letting on, and I was like "duh" then he wants to play a game to prove how good he is, and having seen many a good player in my day I finally get him to let it drop.
Not wanting to let me get away without winning something off me(is that a big deal with hustlers), he basically won't let me leave until I gamble with him so he wants to bet me $40(I think I only had $40) on a coin flip, I'm reluctant so he wants to give me 2:1 odds $80 for $40, I can tell he just wants to win some money so I feign reluctance(hell I am a science major I would never turn down positive odds on a coin flip) and get $90 for $40.
Coin flip goes my way(actually I can fake the toss but it was totally legit), and he wants to bet for $100(I figure the original $40-$80 was so he could win $20 off me on second bet), I win that toss too(all legit) and get the money but he swipes it and claims I am rigging things either with my coin or toss.
Anyway, he makes a little stink then says he needs to go talk to his friend at the bar(road buddy)... I'm not one to let it drop so I get him back over, talk to him and seeing as I was not even a local and he had a buddy, I talked him into giving me the $90 and calling it even.
His voice changes, he's now from new york(not a suprise to me) and he gives me some good advice: "Everyone will try to screw you if given the chance, everyone".
Long story short, I always keep my hands near the money and I'll only gamble in situations I have a good out if the better decides to strongarm..
Other than that I'm a good read of character and can usually spot them a mile away....(hell I spotted him but you cant turn down $40-$90 odds on a 50:50 flip)
whew... thats about it... anyway that was more strongarmed by a pool player rather than hustled at pool, but hope you dont mind the space..
In any case, if its a hustler be wary of ANY propositions they make as they probably have a way of getting out of it if needed....
