Most of the people goes to ATM once in a week or atleast once in a month. I have seen lot of people opt of generating hard copy of the receipt and throw it immediately in trash bin. Instead they can opt for onscreen viewing which save paper.
Don't think that it is small peace of paper. Because, I have noticed that everytime when i went to ATM, the trash is full.
Please avoid this. Also opt for e-statement for your account rather than hardcopy. I have done this for my credit card, salary account and mobile bills. I am not able to do much with my broadband service provider(BSNL), since they don't have have facility.
Cheers,
