A polling device (10) includes a housing (12), pushbuttons (14, 16) mounted on the housing for receiving customer responses to an inquiry, circuitry for counting and storing the number of times each pushbutton (14, 16) is depressed, and a time delay circuit for disabling the counting circuitry for a predetermined period of time after one of the pushbuttons has been depressed for discouraging repetitive voting. A display unit (46) for reading and displaying the number of times each pushbutton (14, 16) has been depressed is also provided.
