Photographic industry

i was asked, it's easy for me to say no as when it comes to the business side of things i have heard it all before "there is a really big job coming up" "can you just shoot these as well" "we want complete copyright" etc etc. i don't fall for any of it and the legal side of my paperwork is watertight.
a fellow photographer who helps put these articles together asked me if they could use the image. there is no fee and i'm happy with that. for a couple of reasons.
They were upfront about it and it can only be used in that article.
it's a bit of free publicity for me
If i ever have any problems with a canon product in the future i will use the line "i can't believe you are not honoring the warranty but are happy to use my images for free" (hopefully this will never happen)
I'm unlikely to use the image for anything else.

I doubt there are many contributors to this thread who have Terms and conditions attached to their invoices that take up a whole page and issue usage licenses for each image they sell.
to call me a mug suggests i don't know what i'm doing with my business. i'm confident that i do know what i'm doing otherwise i wouldn't still be in business.

jeebus i was raised by a contract lawyer and i thought i was obsessive about legal documentation.
