Members start arriving at 11:45am, check in, gather in fellowship and go thru the buffet line for lunch.  Anywhere between 12:20pm and 12:35pm the President convenes the meeting.  Announcements are made and then the speaker is introduced around 12:40pm.  Many Rotarians have commitments immediately after the meeting and after 1:00pm it is expected to see Rotarians leave even if the speaker continues past the 1:00pm deadline.  It is best to conclude 2-5 minutes before 1:00pm to take questions.  Most speakers offer to stay afterwards and answer additional questions of those able to stay.  It is unusual for additional questions to last past 1:15-1:30pm.
