Shop-clean??? I don't understand?

Right now it's hard to find my building board under all the tools and left overs. I have to finish sand the model I'm working on right now then I will clean up and remove all the balsa dust so I can cover the newest creation. Truth is I clean the shop about three times during the build but it is cluttered A lot between cleanings.
I have the time to build 10 hours A day and sometimes I do but lately I have just been going out and working maybe an hour when I'm in the mood then maybe doing nothing for days on end. The job always gets done though.

I can understand younger people not having the time but most of the guys I have built for are retired and know how to build. They want that kit built but don't want to do it themselves so they pay me to do it?? There reason is always the same, they don't have the time?? I don't mind though until they ask me to do repairs on there broken ARFs for them. I don't do repairs, I will assemble there ARFs and set them up for them but that's as far as I will go.
Why someone that is retired needs me to assemble an ARF for them still leaves me baffeled???

Oh well, it's money in my pocket.
