Stupid commercial rant Pt 2

Yet another Liberty Mutual commercial is bugging me. In this one, a older gentleman shuffles over to answer his ringing phone. On the other end we hear a youthful voice ask if this is Walter. The old man says yes. The young man then says he thinks he's found something that belongs to him. Walter asks what and the young man says, kinda condescendingly, "Sir, if you look out your window I can show you." Walter shuffles over to his window and looks down to see a smug-faced young man waving a wallet over his head. The LM announcer then kicks in with all that nonsense about responsibility and doing the right thing.

Questions: how did this punk know Walter had a front-facing apartment in that high rise? What if Walter 's big window was on the side (like mine) or in back? That kid would have looked like a damn fool if Walter had said, "All I see is the dump." And why didn't he just say, "Sir, I found your wallet and I came to return it to you" instead acting all self-satisfied with himself for driving over to personally return it to him. I mean, it's very nice of him, but it is less 'I'm so awesome' about it. For that matter, why didn't he mail it to him? I've found IDs before and put them in an envelope and mailed them to the person missing it because that's decent. Perhaps he wasn't doing the right thing as much as "hoping for a little reward."
