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 ...

They're not comparable but the scenario is very similar.
Banks with their ATM target public places to make access to cash easier and at the same time, to make some profit too. So, there's nothing wrong if slot machines are being installed on public places to provide comfort and entertainment

And yes,
Slot machine eat your cash and in some cases, help you with cash so you can visit the ATM to get some cash.
