Hang on a sec...
Once you have the ATM installed, what costs are involved that would make it so unprofitable you would remove it just because your fee is reduced by 5c per transaction?
A Little bit of electricity? An Internet Connection? It's surely not going to use much of either. Getting the machine restocked each day/week? But surely that would be an on call type of thing, so you only restock once the machine is empty (or close to), and if a full ATM getting emptied isnt profitable then that 5c reduction isnt going to change anything.
Me thinks, I hear a fearmonger at work - "Oh no 5c less per Transaction? We'll end up with an ATM-apocalypse..."
