Business etiquette?

Dear sir:
I would like to extend my congratulations to Vic Nowak and the rest of the staff at Family and Children’s Services on their upcoming move to the old Fort Frances High School site.
I enjoyed my time working for this wonderful organization, and am sure the staff and service users will be pleased with the increased accessibility.
I was surprised at some quoted comments, however, and had to peruse the web for business etiquette tips.
From what I found, it would be beneficial to thank a tenant for 20 years of patronage rather than use local media to publicly chide them. But then again, perhaps that’s why I’m a poor social worker and not independently wealthy.
Congrats again.
(Signed), 
Bob Conlon
