I would of done the same, unless it was a big job.
The reason I say that is I cleaned a big farmhouse in and out on Monday, the ladies husband had just died and she was preparing for the wake.
Whilst I was doing the insides we were chatting and she was literally crying on my shoulder, it was really awkward. She was telling me how the business has gone down the pan and the only company she has now is her dog.
I felt really guilty asking for payment at the end, but the job was a big chunk of my days earnings and was hard work, it was to much for me to just give away.
