BF: Humans there is a time to pet us on the head and a time not to. When you are eating is NOT one of those times. Your hand should go below our mouths so we can lick food you may have sticking on your hand. We cannot lick the top of our heads. Also take your thin last finger which seems to have no purpose to a good purpose by sticking that finger into the food so we can lick it.
GF: No. You can pat him on top of head this way I get to lick off the food. His advice on your thin last finger is good advice. Those fingers seem utterly useless.
