Had a Customer who complained that the Wi-Fi in one of their conference rooms was "always" unreliable. I checked it multiple times and didn't find any problems-- low SNR, strong signal, low airtime utilization.

Eventually I learned out that "always" meant a particular recurring lunchtime meeting, scheduled right when a steady stream of workers were going into the break room across the hall and heating food in a microwave oven.
