Stop in for a cup of coffee

Customer stopped in. He seems happy with the progress. Indicated at somewhere around the 200 hour mark is what is in the budget for me. I dont want to be in it for that long, but it is what it is. So a coffee then back at it.
I charged my BIL a grand for re wiring his Blazer. He balked. WTF do people think time is worth? I had over 100 hours in to it...
