Cash Machines and asking for the amount you wish to withdraw – Why ?

How come at a cash machine or ATM if you press the ‘Other Amount’ button do you need to enter the dollar and cents value?

Do ATMs give you small change? I don’t think so. So why can I enter $23.55 as an amount to then be told it needs to be a multiple of $20 or $50 notes?

Why give me an option that I can’t make use of? Its all about the user experience people !!!!! Give people the option and they will try to use it. Why offer it if you can’t make use of it !
