Should I pay my real estate agent for a deal that didn't work out?

[Arthur E.]

Long story short, my real estate agent and I have been chasing after a deal for about 2 months and now it's looking like it's probably not going to go through.  This deal has been a huge pain for everyone involved.  My real estate agent has gone above and beyond the call of duty on doing everything I've asked her to do and I feel terrible about her walking away empty handed.  I would never be able to afford to pay her for all the time she spent on this, but I'm wondering if $300 would help her feel better about all the time she spent on this?  Am I crazy?  Should I do this?  Would you do this?
