Recently an admin staffer helped me close a deal simply because the retail client (one I'd worked with a fair bit previously) called her directly to finalize some paperwork after delaying previously. The admin person is now half-joking about me giving her a piece of my comp. I think if anything this would be limited to a bottle of wine or something, because it isn't a big deal. I still did 95% of the work. My name is on the deal and it's my risk. The admin person will probably have to do this exact same thing again in the future for me or other IR people simply as a part of her normal duties. She is compensated fairly, I assume, and does not otherwise earn commission. Do I owe her anything?
