If you are talking about physically I think not. Whens the last time a player ever got hurt bad over something like this? Not Little Wonky down the pool room either but a name player. People like to talk some shit but nothing ever happens. Absolute worst case is a black eye. Way more guys have been knocked out over saying something stupid in the bar than any mythical gambler revenge.
I just hope you're right. Nothing ever happens, until it does.
