Luckily, we might not have to ponder these things anymore, something for which we are entirely grateful as it'll allow us more time to ponder more meaningful questions such as whether to watch "Heroes" or "24". That is because Supervisor McDreamy, Ross Mirkarimi, is mad as Hell about the big supermarket chains dicking around on his earlier legislation and he's not going to take it anymore. So he's calling for steep penalties for any supermarket that does not offer recyclable, compostable or reusable check-out bags.
If you remember, the earlier legislation called for supermarkets to send in numbers about how well they're complying with environmental rules on bags. They didn't really do it. So now Ross is throwing more weight on them to comply. To sweeten the pot, he's also thinking bout giving the supermarket chains rebates to help make them want to comply. Ah, it’s the old carrot and stick policy.
One could argue that this being a free country, we should have the right to use any bags we want, even if they happen to be made up of baby seal fur. But in this case, we're more than happy to let somebody else make that decision for us.
