A Few Words About Receipts

I just got a receipt from the grocery store for a half gallon of orange juice that I purchased with cash. It was eight inches long. Another receipt from the other day, with two items purchased with cash at the grocery store, nine inches long. Is there a reason I need such a huge receipt? Especially for the grocery store. Don't even get me started on Best Buy/Circuit City/CompUSA where purchasing a single electronics item (like a DVD) nets you a twelve inch receipt that includes the entire store policy on it. Can I just get a little receipt? These big ones are a waste and just impractical.
