If it was as simple as charging him for 8 hours of painting, id do that, but it isn’t.

The job has taken another 4 hours due to something going wrong and I’ve needed to re paint stuff, and I don’t know whether to charge him for it or not?

It also doesn’t help that he’s been talking to me a lot, which I’ve forgot to time, as well as giving me loads of coffee and food.

Advice?
