I didn't buy small bin bags before but now I sometimes do, carrier bags are the perfect size for bedroom, office and bathroom bins. I must get into the habit of carrying around a cloth bag! What really peeves me off is marks and spencers. They seem to always try and give you a small bag if you buy just a sndwich. Surely with they're 5p bigger bag policy that they say is for the ennvironment they shouldn't so willingly try and force a small bag on you, I have to request that they take my sarnie out of the bag again. They always seem so shocked and sometimes so, no it's alright they're free. Then there are the M&S shoppers who refuse to pay the 5p and insist instead that they be given a couple of the smaller bags.
