There used to be a chilling device as a party store near my house. There was a tub of super-chilled green or blue liquid that was in a whirlpool of sorts, and you could dunk your just-purchased drink in there for 1 minute and it would be cold when you took it out.

But doesn't beer benefit from always staying cold?

Beer does not benefit from always staying cold. If you get bored, it is relatively easy to do a double-blind test.

...but if you have a bottle conditioned ale, sometimes you can tell the difference because the 'warm' one can reactivate the yeasts and change the flavor slightly.

Not really. Some people call it "skunking" when one keeps changing the temperature of bottled beer, but it's harmless. Real skunking is exposure to light.

Pool of antifreeze? Who cares! In all honesty, a shared tub sounds like a horrible idea.

I'm sure the outside of your bottle/can has seen worse horrors than that. If you are concerned by that sort of thing, you should probably make a habit of wiping them off before consuming anyway.
