This would certainly be reason enough to leave a game.
Not that I ever swallowed snuff as a child and would know first hand)
A buddy of mine was working on a ranch. He was 12 yrs old at the time. This cowhand he knew was chewing, and offered him some. My buddy took a pinch, put it in his mouth, and after a moment, he asked the cowboy if he’d like a Coke. He left, walked straight up to his room, and fell on his bed. Sleep for a few hours. After waking up, he went back out and saw the same cowboy. The guy asked, “Where’s my Coke?”. :^)
That was his first experience with chewing tobacco. He never forget it.
BTW, pardon the typos. Must be the chewing tobacco.
