As long you dont hurt others or making yourself hurt or something in between two then i dont see anything wrong with it.People are just too judgemental on what others been doing.
I also don't understand why other people are taking things seriously if someone uses the art of Fengshui in gambling.
After all, these people that use lucky stuff take care of their bankroll. Why other people should bother with that?
Correct. Let's just mind our own business and let these people just do what they want.
