Yesterday I told my hubby about chemicals on paper receipts, and how they are absorbed through the skin. He thinks I'm a little OCD about the whole thing, but it's as easy as saying "No thank you" when offered one. Then I proceeded to clean out all the old receipts from my car... with my hands... but from now on it's "No thank you!" An added bonus... less clutter in my car and purse.
BPA in store receipts
EDIT: I recently learned that Chipotle uses BPA-free receipts. Just one more great thing they're doing.
