The Birthday Bootlegger - S20-E8
Other mistake: Stella is deaf and lip-reads. When Preston announces he can allow office birthdays again, Stella immediately cheers at the exact same time as everyone else, but from the camera angle, Preston is standing in front of Stella and facing away from her.
Other mistake: The guys lasso the bear. Then Peter impossibly lassos the bear's legs. There's no way for the lasso to go around the bear's leg with his feet on the ground. And the lasso couldn't have gone over the body down to the legs since the other ropes would have gotten in the way.
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.
