Hey Jen! My take is that it might be a touchy conversation. Not the conversation as such but the timing. Negotiating a fee after the fact hasn't worked well for me in the past. That being said, I'd try to come up with my total cost (gas, sugar, OA, etc) then add a percentage of that cost to the total. So your cost plus 10, 15, 20, 25% for your time and trouble. Just my thoughts on it. Best of luck, Ted
