Ethics Question: Do you "say" there are other offers?

[Mindy Jensen]

This question comes out of frustration over the seemingly ubiquitous "We've received another offer, please give highest and best." 

I live in a hot market, and it seems whenever I call about a property, there's always "another offer."

As a listing agent, it is my duty to get the best deal for my client, but it seems like sometimes the other agent doesn't actually have another offer. 

Your thoughts?
