Thermal Dueling

During the summer our office is kept comfortable but not unreasonably cold, yet several of my nearby coworkers require portable heaters under their desks for cold feet. This seems counterproductive and inefficient, since running these heaters raises the temperature at my end of the office by several degrees, thereby forcing the cooling system to work harder against that warmer air.

Instead of heaters, I propose that they should be given pairs of slippers, and if they are still cold, a quick step outside should warm them up quickly enough, on a day like yesterday or today.
