Grocery/Gym Bag

My reusable grocery bag sometimes doubles as my gym bag. I'll admit this is not an ideal marriage of uses. I only use the bag for groceries now right after its come out of the wash, but I still feel a little grossed out so I gravitate towards buying groceries that are all canned or wrapped in plastic. And I suppose that kind of defeats the purpose of carrying a reusable grocery bag. On top of that, half the time I bring the bag to the grocery store, I'll forget that I have it until the clerk packs a plastic bag full of my stuff and I walk out of the store still carrying my grocery/gym bag over my shoulder.
