Quoted from LTG:The amount of change you need on hand would be staggering. Take forever to count at the end of the show to split. And run game owners ragged with stuck coins and what not.
And add break ins to games to the list of problems.
An idea, I just don't think it would work or be easy.
LTG : )
I'm also thinking that anytime the owner of a game had to open his pin up for whatever reason, they would be accused by someone of taking money.... I agree; when I go to a pin show, I like my games on free play.
