Wait, what?
What do you mean'wonder'?
You are billing them for it, right?
On the smaller low budget jobs, sometimes I do and sometimes I don't.
If the customer is an ass and I clearly see they have the means, they get a bill.
Elderly couple that is nice (just very forgetful) and living on a tight budget, I enjoy the extra talking time with them and thank them when I'm all done.
