One like doesn't sound rogue. If the dude'd gone out of his way to like every claim of Tibet being its own country, sure. In this case though I'd imagine he saw a "Thanks Marriott" and liked it because that's the thing companies do. I've had companies miss my oozing-in-sarcasm messages and like them in the past even. The thing to think about is how much time does he really have per action? If it was you on personal twitter, minutes per action. As a customer support person answering hundreds of messages a day, probably closer to a second or two per action
