He asked about whether or not it is bad ETIQUETTE, not if it was legal..... And this has flown straight past "bad etiquette" and into the realm of whispers and awkward glances saying, "Umm...is he retarded or something? "
Also, I'm with Andy on this one.... I still can't believe that his question was honestly asked. This guy is either a total newcomer to golf (I guess that explains the lying-6 on a par three and still away), or he has a serious lack of normal social behavior.
I imagine that he's probably the kind of guy that, in an informal friendly pick-up basketball game, will launch the ball squarely into a complete strangers nose from 3 feet away. Then as his defender crumbles to the ground he yells, "HA! heads up!", as he dribbles like a toddler towards the goal, proceeding to nearly face-plant as he attempts a 'jumpstop', and then pushes the ball with both hands into the under-side up the rim....
