Bag for Life Top Trumps revisited

Now that England has joined other parts of the UK in charging 5p for a 'single use'* shopping bag, I thought it was worth revisiting a middle class game I brought up a while ago, especially as I have since discovered an additional, powerful card to add to the pack.

As someone with green aspirations (come on, I did write  Ecologic ), I'm all in favour of supermarket 'bag for life' offerings, which mean you reuse your bags rather than throw them away. However, I think it is boring, and quite possibly in bad taste, to use a bag in the shop from which it was obtained.

Instead, to keep the shopping experience amusing, the good middle class shopper should play a game of Bag-for-life Top Trumps®. The idea is simple. Always use a bag with snob value at the supermarket in which you are shopping. So:
In Aldi/Lidl use at least an Asda bag**In Asda use at least a Tesco bagIn Tesco use at least a Sainsbury's bagIn Sainsbury's use at least a Marks and Spencer bagIn Marks and Spencer use at least a Waitrose bagIn Waitrose use at least a Booths bagIn my previous list, Waitrose was top of the food chain (geddit?), but I have since discovered the North West-only chain Booths, which makes Waitrose look common.
But there is still the final problem. What to do in that doyen of supermarkets? Not a problem at all, because there is one bag that trumps them all - a French supermarket bag. In fact it's best to stick to one of these at any store, then you don't have to worry about whether you are properly attired. You can turn up in your pyjamas, a deer stalker and a tutu and still feel superior.

* I'm always a bit wary of the term 'single use'. There's no doubt that this kind of usage tax does significantly reduce the number of 'single use' bags issued by supermarkets, which sounds very green. However, there was some evidence from Ireland, when this approach was introduced there, that the consumption of the plastic film going into plastic bags went up, not down. This is because many people actually re-use 'single use' bags for other purposes, e.g. bin bags, food bags etc. As they then had to buy 'real' bin bags etc., which typically use significantly more plastic than the equivalent 'single use' bag, the impact seemed to be to actually increase the plastic (by weight) going into waste.

** Having said that, there's a bit of inverse snobbery that means that bags from really cheap places have a slight cachet that lets them play up a level or two. But they still don't work at Marks and Spencers and above.
