Idea for a short story
A bar owner is surprised to find that almost no one is coming to his bar in the height of summer, despite the air conditioning he has had installed. Instead they are all going to a bar that he knows has no air conditioning, even though the heat is oppressive and maddening. He visits the bar and discovers that the bar man there has developed a cocktail that actively lowers your temperature from the inside. Everyone is queuing up for this sweet release and getting progressively drunker and drunker. And colder and colder. So cold that they light a fire and start having a Christmas celebration in August. In the end all the patrons are found dead of hypothermia in the middle of a heatwave, but all smiling.
