The Most Interesting Man in the World - S12-E17
Revealing mistake: When Peter is attempting to sneak into the Drunken Clam whilst keeping an eye on Stewie, Peter rips out his eye and throws it towards Stewie, though his glasses are in the way of his eye. (00:03:10)





Suggested correction: Quagmire considers the rest of them to be his best friends. He isn't drinking because they can't drink. He is complaining because since his friends can't drink - he won't drink, so he is still pissed.
It's still a plot hole considering Quagmire's age. I think the writers messed up big time.
You make a good point, but it's awkward to be that one person who is drinking while surrounded by people who can't. So, I understand the correction that was submitted above. Because his friends are not drinking, he now feels that he can't.
It's 100% a mistake. Quagmire simply would buy them alcohol the same way Brian did when they realized he could.
