These parents are full of crud, if you want my opinion (or even if you don't). If their kid doesn't believe in Santa, why would it bother him that the driver is wearing a Santa hat? He knows it's make believe anyway. Do his Mom and Dad think they can protect him from other sorts of outrages, such as bell ringing and mall Santas as well? This child is in for a real shock if he's being raised with the notion that Mom and Dad can make any problem go away, no matter how trivial.
