with ref to the 5p bag tax, don't panic!
it really isn't a big deal and is actually a bloody good idea that is very easy to adapt to. Though I note for some reason the english are being given at least 18 months warning to get used to the idea, not sure why? Oh, and deciding it will only be certain types of shops, that's a bizarre thing that can only lead to stupid headlines about two shops next to each other, one has to charge, one doesn't. Keep it simple, 5p per bag.
