I don't know what the agent is thinking.
Probably isn't !As a Professional Courtesy, I would probably call the other Broker and suggest that he/she review the rest of this Agent's work to make sure they don't have a complete mis-understanding of how things work.
A pattern may be revealed which will demonstrate that this IS NOT just a simple TYPO, and a little "in-house education" may be in order.
That call will eliminate future problems down the line. The individual Agent need not know "who" snitched; it's for their own good.
I'd appreciate the return favor (if we ever made a mistake).
