ATMs

Today withdrew some money from ATM . I needed the cash in 500/- notes but the machine spewed 100 bucks ones making my wallet quite thick which is the last thing which I wanted. Why cant the ATMs ask for denomination of currency we need.
On second thoughts, it would surely complicate things.

How about a cashless money transaction process even for small things like a rickshaw ride. May be I am becoming too utopic.Still a long way to go
