Search Results: just want to be his friend

I have known my friend Rich since 3rd grade. We grew up together but took different career paths. I went to college and got a degree in business. I got an alright job, but nothing to get excited about. Rich screwed around. He took the first job that was offered to him as a favor from a friend. He hated it and complained every day. By his own admission, he was terrible and close to being fired a few times. He did the bare minimum and cut corners whenever possible. He was also one foot out the door always. Then a different company was in desperate need of a logistics manager, and they did not know his work ethic. All they knew was he had enough experience, and he knew all the lingo to ace the job interview. By his own admission, he conned them into believing he was something he isn't.
I was happy 4 him. I believed he would straighten up, and it would be good for him. He didn't change and was a terrible manager, his words. He would talk badly about his employees to me and curse them for doing things he would do himself. He would hide and sleep on the job or get caught up on Netflix, or take an hour of work and turn it into his whole day. Still, he complained constantly and talked about how bad the company is. He felt justified because they were terrible in his eyes. He also constantly complained about leaving.
Now, he has lucked into the same opportunity. A new company is looking for a senior logistics manager, and he fits their needs based on his experience and his LinkedIn profile, which is made entirely of lies. He was just talking about quitting and, and now he is acting like he is a prestigious senior manager. He admits that this is undeserving, but he will still expect me to make a big deal of it and take him out for a drink. I don't think he at all deserves this, and I am kind of disgusted that he keeps lucking into these promotions. But what are my options? Do I have to just pretend to be happy for him, or can I get away with just a congratulations and drop it?
