Remind him that he would last 10 minutes in a real casino doing this.

If he is an experienced player, it is completely unacceptable and I would say so.

If he is a newbie, it is understandable. For a table with a lot of newbies in a home game situation, I would institute a rule where everyone has to flip over their cards at showdown and during all-ins.

1. When he is in the middle of his backswing, yell "all-in!".

2. On the green, pick up his ball and say "wow, Titlist Titanium, nice ball" and toss it 4 feet further away from the hole. Be sure to step in his putting line repeatedly while spinning around.

3. On every one of his shots, give him advice on club selection.
