My chameleon used to drink in front of me, but he doesn't all the time now. He used to drink from a dripper but he won't now. Sometimes he runs away from the water but it's tough luck for him, I keep misting anyway. Sometimes he extends his tongue to catch water like he would crickets, although to me that seems less efficient than just drinking from the leaves like he used to. I don't know why he has developed this latest behavior, but he has been kind of weird all-around. One thing I have learned is that they will wait for you to leave to do what they need to if they don't want to do it in front of you.
