Plastic or... plastic?

I personally love grocery shopping in Italy. The variety and quality of the food available is simply excellent. If you are used to shop in US stores, you may notice a few differences:
- Carts are free to use but you often need a Euro coin deposit to unlock the cart from the rack
- At the cash register, you'll have only one option: plastic bags
- Bags are subject to an 'environmental' fee of about Euro 0.05
- No one will help you place your groceries in the bags
