I walked in to work this morning like I would any other day. I stopped by the front desk and chatted with Liz about the weather. My friend and I exchanged the events of our weekend and moved along, just like we would any other day. As I walked to my office, which happens to be the last one in the hall, I opened the door and instantaneously knew that something was wrong with the thermostat. My office had clearly not gained any air circulation all weekend, as the air was thick and stale. I set down my things and tinkered with the digital thermostat for a minute or two until returning to the front desk. I asked Liz if she was aware of any concerns with the AC in other offices. She clearly had not gained any other complaints. She was confused and asked if I was sure the thermostat was not set to a higher temperature by the cleaning crew. They tend to adjust the thermostat to weird temperatures from time to time, so of course, that was my first thought. She walked back with me to my office and was instantaneously stunned by how hot the office had become over the weekend. She looked at the thermostat and did the same thing that I had already done. My friend and I called the Heating plus Air Conditioning specialist to come in and take a look. The earliest appointment was not until the following day. I opted to work in a odd office that day. The AC was back to normal working order the next day.
