Lukewarm Science
Coffee Shop | Indiana, USA | Right | May 7, 2012
(A customer orders a large mocha, but only lukewarm. After receiving it, she takes a sip, grimaces, and sighs.)
Customer: “I really miss hot coffee.”
Me: “I can heat it up more if you like.”
Customer: “Oh, no, it has to be lukewarm. I’m trying to lose weight. I read that calories are a unit of heat!”
