I am asking because this is what banks have turned to, having their ATM machines installed in public places to have people use them for withdrawals on the go. What are you thinking?
Really? Why compare it to an ATM? That doesn’t even make sense. An ATM
gives you cash, while a slot machine
eats your cash. Totally opposite ...

An ATM machine generates income for the bank that has had it installed, so also can a slot machine generate income for a casino or game provider that has it installed, that is where the comparison come in.
