Yes, those damned space heaters. I've worked in some buildings with really uneven air conditioning so what can you do, but I swear some of it is they just can't take cool air blowing on them whatsoever. Others would continuously ---smurfette--- about how their coworkers are going to burn the building down.
I finally had had enough of it at one point, had the secretary order everyone a thermometer that could remember the highest and lowest temperatures it had encountered. That was actually quite the eye opener and we dragged in our AC contractor and wanted to know why EVERYONE'S office was peaking over 80 on a regular basis. Prior to a thermometer stationed in each office he kept pawning it off as "overly sensitive women" and "some rooms are just a little warmer than others." Last excuse I heard was, "I installed an AC unit for the number of people in the building, not the square footage." When that underpowered sucker blew, it hit 106 in my office.
