Don, I was 6'5" and 250-270 in the 70s when I was doing this. I never had any trouble, "That Way". Frequently, for what ever reason, they wouldn't play but it worked well if the sucker had been hitting on the same bar maid you just spoke to. Kinda worked on their manhood. At one time, I don't think there was anyone in the country that laid it down like I did. I studyed under the man many think was the greatest hustler ever, Utley J. Puckett. Utley was a big guy too and never had any problems getting out with the cash. Even as an old man, when I knew him. In my opinion, the greatest hustler ever was a guy virtually no one knew, unless you were a true player, Bill Lawson. Bill got me for more $$$ than anyone. Bill had an uncanny knack for shooting combinations on the 9 ball. If you think that won't keep you at the table your nuts. I'm not talking about hanging 9 balls. Middle of the table 9s and this guy would fire a 4-9 combo and split the joint. This was on the bar box, where anyone could run out.
P.S. And, you would have more likely said, "POST". Many did, Don.
