FORECASTING in the HOSPITALITY INDUSTRY
“I’m telling you the average is about $18.00,” said
Maya Stafford, the head server at the Mountain Grill. Maya
and Raktida were talking about the check average achieved
by the Grill on the previous two nights. “Look,” continued
Maya, “on Saturday night. On Sunday, it was about $14.00
because they don’t drink as much. $22.00 plus $14.00 is
$36.00. $36.00 divided by 2 equals $18.00. Say, didn’t you
tell me you went to restaurant management school? Didn’t
you learn anything there?!”
Raktida, the new dining room supervisor (and an
honor hospitality school graduate) was unconvinced by
Maya’s logic. While Maya was a great server, Raktida
thought she was dead wrong-by at least $2.00! To find out
who right, complete the Mountain Grill’s sales history record
below, and then answer the questions following it.
