The only thing I hate about the cards is that most arcades that use it (not all tho) do that bullshit where the cheapest game is an odd number of credits, but you can only buy an even number of credits so you are paying a minimum of $5 for a maximum of a $3 purchase, leaving you with $2 you can't so shit with.
Fuck this practice, and fuck the son of a bitch who invented it.
