Do you use paper, plastic or bring your own?

Here is a link to a previous question that taps on the topic. I was wondering was the mass practices.

We bring our own. My first reaction was that it would be a pain. I found out it was WAY less annoying than dealing with the plastic bags.

My mother in law gets paper and plastic so she can put a paper bag in her plastic waste basket, then line it with a plastic bag so it wont leak. It makes me want to scream.
