OH MY GOD!
He is clearly flirting with you.
All you need to do is figure out if he opens and closes his fingers in a "come hither" motion or if its more of a dismissive "leave me, pleb!" thing.
That out of the way, special treatment is always special treatment. This one might chalk up to be nothing but, if you feel it is something, why not approach him and find out?
