word option. Look it up dummy, no one is suggesting the sole use of credit cards but rather it is another way of payment if you really need it. Obviously it is a slower process, even a dummy like you seems to realise that but as another post says invariably the hold up is immigration not VOA and with this I agree.
Your maths are correct but your reasoning is a bit slanted. If most people were in the habit of paying with credit cards I would suggest there would be more than 1 VOA line and more than 1 machine.
