Buy that agent a steak diner. 

I have a tenant in my SFH whom I saw using a propane grill in the garage of my property in Sarasota, FL.

Tenant is using a propane grill inside garage.

Older homes in our area often have a functioning forced air furnace with ducts for all 1st floor rooms but gravity registers (basically holes-with-grills through the 1st fl ceiling/2nd fl floor) for the 2nd floor.  

I got one of the 14 'inch grill lighters and that got it. 

To really get on their good side, you can also provide a gas grill for cooking out with patio furniture.

I'd grill them on how and where they marketed the unit and if it was lacking give the new PM a shot at it for a month.

One of the best is the Jet event every third Wednesday at the Texans bar and grille in city center.

Its at the RAM Bar & Grill next to the Lakewood Shopping Center. 

It seems like it would be hard to properly grill a sponser about a deal if your are a few thousand miles away and don't know a lot about that particular market.
