That’s because they fully understand the burden of properly doing said job. This is the very reason I’ve turned down many job offers and/or doing something for free. Cuz I know that that will be just another thing on my schedule, which I would ralter not cramp up all the way. Got a family, would like to spend some time with them as well. Helping people and doing stuff for free or for a small fee is fun and I enjoy it, but it doesn’t put food on the table and it doesn’t compensate for lost time with my loved ones.
