Some of us learned stuff 50 - 60 years ago that is not cool now. Or we learned it from older players, playing for the cheese, and never thought about it until the fact that it did not make sense occurred to us when we were less impressionable. Then it's just an old habit dies hard thing. Like after using the cube, you are supposed to flick any loose chalk out (into the air onto the floor

) and place it gently on the rail blue side down for the next player. Just common courtesy! Well it was, some places, long ago....
About them wussie safeties: before TV changed things, heads-up 9-ball was often played push-out option on every change of turn. Now that makes safety duel a real duel. When, exactly, did BIH rule become common for missing a safe ball, in 8 ball? I first picked up a cue in the back of country grocery stores as a pre-teen, then learned in bars, not pool halls, so maybe it was more prevalent. Though IIUC, 14.1 would have been the game in a pool hall at that time anyway?
Probably everyone who has played with a sneaky has a story or 2 to tell about some guy who was overly convinced by the subterfuge that it was a house stick.
