I know this question sounds weird, but here's the information. I got an email from my apartment.
Dear Valued Residents,
Our vendor will be on-site tomorrow, Tuesday, April 25, 2017 to complete dryer vent cleaning for the entire community between the hours of 8 am to 6 pm.
No access inside your homes will be needed. Our vendor will be completing this service through the exterior vents in each building.
To me, a vendor means a person who sells on the street. But in this email, it seems a vendor means a person who maintains our dryer vent.
Is that correct?
