I'm fine (I'd rather have it cold but it's still palatable) with room-temperature lager or even weissbier, but anything else... nah. That being said, when room temperature is 30C, all that goes out the window. I'll shotgun the warm beer at the bottom of the bottle after forgetting it for too long because I hate to waste beer, but I won't like it.

Beer-wise, I used to mostly drink Bavaria 8.6 and could even stomach it at room temperature but now my back hurts and that stomach is not as robust as it used to.
