I found a small place on my new truck about the size of a bb,where the paint has chipped off

. Another little spot next too it about the size of a grain of salt. What could have caused this? A rock that hit me on the road? The lazer wash? Will toyota pay for it to be fixed? You can't really see it and I'm not knocking Toyota, they make great cars and trucks,but it still sucks I spend 30k on a new truck ,less than 3,000 miles later I found a bad spot

How should I approach the dealership with my problem, any ideas?
thanks
