I worked in a truck stop one time and the vendor would put the games in/half-ass maintain them and rotate some new ones in once in awhile and the take out of the coin-box was 50/50. I guess it was figured with using power/taking up retail space and such.
He left the coinbox key in one of the machines one night and we all made copies of it. He had all of his machines keyed the same!!!! Working the grave-yard shift was so swweeeeeeet after that!
