About "double" games, for instance, the two Donkey Kong Junior cabinets.
How can we know that everyone takes their "own" cabinet? Just good trust, or are they marked in some way?
I mean, some cabs are in awesome condition, some others are projects or don't work etc.
I wouldn't like it if someone switched my DK JR and DK with another one, which might be in a lesser condition or whatever. Or the other way around ofcourse.
I have pics of the cabs I bought but don't know if everybody is as punctual about this as I am

How do you guys feel about this?
