Pisses me off. Because I a. recycle my plastic bags and b. walk to the shops. So I need carrier bags. It's all very well having bags for life if you are driving, but they are crap for walking home. If they are full, they are too heavy, half empty and the shopping moves around all over the place. And no, I don't always have spare bags in my handbag - my shopping is spontaneous, I often pick things up as I'm passing.
I'm doing no damage to the environment at all compared to people who drive but the system is going to be changed to make life more difficult for me. Moan moan moan...
