I refuse to hire fats. But I don't do it outright.  All fats are lazy, selfish, creatures.  This will come out if you let it.  Design methods to test for these traits.  We put all perspective employees through exercises meant to reveal negative traits.  Our interviews last a full day, 8am until 9pm, and we buy all three meals.  We push them to go all day, we do simulated team exercises where candidates are moving the whole time, and during our panel interviews we have the candidate stand at a white board and write out thought process for problem solving. Keeping them on their feet all day, moving, interacting, fats lose their temper.  We've never had a fat not end in an outburst, or be so exhausted they couldn't keep up their facade during the late dinner after a grueling day. Never even have to decline to hire them because they are fat.  We can always cite something else.
