well played, well played indeed

So Bryce got another pair of shoes today- pair #4 for summer. While shopping, he takes off his crocs, puts them in my diaper bag, pics up a pair he wanted and takes them to counter. When I asked what he was doing he responds, "pay for it." I then tried to put crocs back on, he cries, "oww, hurt" How do I not buy the pair without everyone in store thinking I am evil? He has more summer shoes then me!
