In an earlier chapter I could explain some of his behavior as being cautious and withholding information on purpose, to gain time to verify the correlation between his game info and the new world reality, but this time he indeed was purely dumb. Sure, it's nice to be allowed to eat in peace, but the fact is he still didn't get to finish his meal without an interruption because he needed to beat the bastard first. He might have as well taken his plate and finished the food standing elsewhere, or something. But of course if he wants maximum fame, as opposed to avoiding attention like he told the businesswoman earlier, I guess this made more sense. He's one of the talk the talk but don't walk the walk guys.
