He's just smug. He thinks he knows better than everyone else, won't take valid feedback on board, got himself in trouble that could've been easily prevented if he'd have just listened to the comments. He's going through one heck of a midlife crisis and the fact he's going back... he just doesn't get it. He looks miserable in Thailand as well. Hot, sweaty, red, swollen, his diet and drinking habits are catching up to him. He spends time with these club and bar owners who look as shady as the next one and he thinks he can make it out in Thailand like them, but he's just too boring and too naive
