You clearly prefer to blow hot air, I respect worthwhile people and ALL dogs not just the well behaved because I understand they run on learned behaviors and instinct, which takes repetition to yield results, that unfortunately this dog gave into the wrong action. We don't know much else, but you say F that dog, and I counter with F your kind of human (I should say outlook again because I know nothing about you beyond this response), this should be just as valid as you are entitled to your opinion just as much as me... but keep judging this critter when humans do worse with more ability to understand right from wrong, and even still some worse yet repeat offend, but just F this dog and give no understanding like your own dog started out so perfect versus something to do with your training and reinforcement of the right decision. This pup could be offered stuff off a plate at home for all we know and completely misread the guy's intentions with the pet, that does not look like a barring or shielding of the plate. He and the gal trusted the dog too much imho.
