Shopping + 5 year old boy = extreme bordem

What do you do to keep your child entertained while shopping?  I mean your boy child who would rather do pretty much anything in the world but shop.  Just a little advice, giving them your phone, might be a mistake.  They just might figure out how to take pictures, and you thought they didn't know how to unlock it, wrong.  At least one of us is smart I guess.

I am very sorry unknowing public.  (but I got a good 15 to 20 minutes of entertainment out of this, so keep your guard up, there could be a 5 year old photo guru out there among you:))
