Write an email to turn down an invitation
You are the purchasing manager at your firm and have received an email from Barbara Sorrels, one of your firm's major suppliers. She will be in town on October 13 and would like to take you out to dinner that evening.
However, you have an early morning flight on October 14 to Kansas City and will need to pack and make last-minute preparations on the evening of the 13th. Write an email to Barbara declining her invitation.
