It would certainly not be fair, for us at St. Guthlac's, to award the prize to the first all-correct entry submitted. Each of our quizzes is on sale for six months so that some entries are returned whilst we are still selling. All the all-correct entries are numbered with cloakroom tockets, the stubs are put into a bag, and a winner drawn in front of a number of witnesses. A second draw follows with all entries submitted, whether all-correct or not, for consolation prizes.
The answer sheets are prepared & are sent out with the marked entries to all who have sent stamped addressed envelopes. What can be fairer than that?
