Coffee Photographer

I opened my email today and found a request from another user to use one of my photos on flickr. An intern at NowPublic.com is doing an article on the health implications of coffee. While something like that has never happened to me and I was flattered at her admiration of the photo I took in the grass yesterday at the William's BBQ, I turned down her request to use my photo with the Starbucks logo and offered another photo without a logo instead. I was a little worried that I could be held responsible for contributing to an article that might have negative implications on a large corporation such as Starbucks. In the mean time, my head has swelled just a bit. I'm thinkin...perhaps I should try a different career path...Photography perhaps?
