Any fool who drinks Coke on a regular basis has surely realised by now that 70% of the quality taste of coke comes solely from the serving temperature.
Any such fool has also come to know the deadly situation which arrises when one inadvertantly becomes preocupied with coding/borowsing/reading/etc for the next 5 or 12 hours.
When you regain conciousness you will take a sip from your glass, just as you did (what seemed like) just a mement ago! But the ice cubes are long gone, the beading condensation running down the glass, is no longer there to begin dripping away as you wrap your fingers around the glass. The endless supply of tiny bubbles rising to the surface has baan exhausted! These are all signs you should have picked up on, but at 6am who can blame you? So you take a sip...
At this point the body's natural defence will usually deploy a rapid gagging motion, and the bile will start to rise to your throat. If you're one of the strong ones, and you spit it out fast enough, you might just get off with a warning...this time.
This my friends, is the phenomenon of Warm Coke!
