Dear ________________________
Thank you for affording me the opportunity to meet with you and members of your staff.
I know that ____________________ (ex-salesman) serviced your account for many years and made many friends at your firm. While his presence will be missed, I can promise that you will continue to receive the fine service that has always been afforded by _______________________ (firm)
The hospitality you showed me yesterday explains why _________________ (ex-salesman) held your organization is such high regard.
