When the manager of a Wal-Mart thinks his store is a bit too warm, he can't just adjust the thermostat.

According to the Wall Street Journal (pg R4, 8/27), he instead must contact indoor-environment technologists at W-M world headquarters in Bentonville, Ark., and answer a series of questions, "such as the exact spot in the store that feels too warm and whether there are any obvious problems with the ventilation system."
