Formulas are derived for moments of the number of refused customers in a busy period for the M/GI/1/n and the GI/M/1/n queuing systems. As an interesting special case for the M/GI/1/n system, we note that the mean number is 1 when the mean interarrival time equals the mean service time. This provides a more direct argument for a result given in Abramov.
