Just that really.
I don't have an issue with the bag charge, I think it's good to encourage people to use them less.
I don't take plastic bags to the supermarket because I have a backpack that I use but sometimes I like to buy a few because they do come in handy for 'stuff' like lining small bathroom bins, separating wet swimming stuff, things like that.
But virtually every supermarket around here doesn't seem to have them anymore! They have replaced them all with massive, thick 10p bag for life types which are not so good for certain tasks.
Aibu to wish they would just keep both types so we can choose?
