I think many of us regularly spend some time waiting in a queue for the till in grocery stores. And so do I. And in my country they sell disposable plastic bags so you can buy one or whatever quantity you need and pack all the stuff you've bought in it. And almost every evening I meet the same people in my local grocery store buying new disposable plastic bags. New, every day... Of course it's very convenient not to carry a used disposable bag or reusable grocery bag (not plastic of course) with you. But I do it and when I day by day see the same people buying new plastic bags I feel myself slightly irritated, because a lifespan of these bags is way less than an hour. We use too much plastic in our every day life, almost all goods we buy are packed in plastic or made of plastic and isn't it a good idea to reduce this amount at least a little bit by forcing ourselves to stop using disposable plastic things like grocery store's bags?

What do you think about this idea? Do you use disposable plastic bags? If so, do you use them several times? Is there any country where disposable plastic are already forbidden or party forbidden?
