An electrocautery device comprises first and second continuous loop electrode structures. The panels are configured to constitute a portion of the sheathing of a building or an internal partition. The detected restaurant customer service related information is transmitted, preferably, over-the-air to a central computer unit having a receiver for receiving the detected restaurant customer service related information transmitted by the sensor modules over-the-air. In some embodiments, the method can identify malicious behavior and accordingly adjust the trustworthiness value for raters associated with malicious behavior.
