ABSTRACT:
A food product scale system includes a customer detecting functionality and a voice functionality for outputting one or more audible voice messages when a customer is detected. When a customer is at a first distance from a weighing station of the scale a customer attracting message may be output and when the customer is at a second, closer distance from the weighing station an instruction message may be output. Other electronic devices may utilize a similar staged message feature.
