lol....I wonder if it charges him a fee
you can buy your own ATM like that for about $2K. you then fill it with your own cash and set your own fees. he probably has some kinda override when he wants to get cash for himself. then when his guests use it, the money+fees get deducted from their accounts and deposited into his. nice way to make a lil profit if he has people gambling at his house.
if he has a free machine though (which I doubt anybody would loan him, since it probably turns a sh*tty profit in his house), the owner of the machine would put the cash in it and let him set the fee. then they'd split the profit. so yeah, he'd probably get charged about a dollar or sumthin for using it himself.
either way, it seems like a cool idea for safety and convenience
