The secret to taking kids anywhere

I think I have found the secret to taking kids with you to the store. Quarters. Take plenty of quarters and reward good behavior with a stop at quarter vending machines. It's a small price to pay for being efficient at the hardware store with a three year old. Also task the little ones with asking an employee if they stock some bizarre item, like onions at an auto parts warehouse. It gives the child a real feeling of purpose, and is amusing for you. : )
