A multi-function customer satisfaction survey device, system and method. A plurality
of stackable tip trays in a restaurant each include a survey device and a calculator.
Survey questions are presented on a display screen, and a survey keypad is used
by the customer to enter responses. The responses are stored in a memory in the
tray. The trays stack on a base unit that simultaneously collects the responses
from the stacked trays, simultaneously programs the stacked trays with survey questions,
and simultaneously recharges a battery in each tray.
