Fore, please

So the guy in this pic is Ming, a random guy I got paired with. He was walking, and after nearly every shot, he was talking on his phone. Not really sure what he was doing, but as we got to the 4th green, he realizes he doesn't have the phone any more. So he took my cart back down the hole while I putt out, he comes back a couple minutes later, he can't find it. He brings my cart back, tells me to go ahead he needs to go look more intently. So I play on and come up to the green on 7, which is right near the 4th green, where he is now putting. He sees me and yells, "found it!" I tell him good job and give him a thumbs up and on I went. I wonder how he ended up playing.
