Conventions of my Genre

For my initiating action project, I want to write a letter to dining services. I found a couple of examples online of various letters written to promote change or awareness. The first letter was written by a disabled restaurant patron who had difficulty maneuvering around the restaurant. He wrote to the owner asking for improved accessibility in the restaurant for all wheelchair users. He introduced his argument by starting with a narrative of his own experience at the Westside Diner. The second letter I found was written by a citizen addressing a newspaper editor about the harmful affects of chemicals in perfumes. Her argument was supported by facts about the Clean Air Act of 1980 and scientific research about the health effects of these chemicals. I think my letter addressed to dining services would be more like hers because I must compel my audience to act via fact, and not anecdote. From just looking at these two samples,  I see that there is much freedom in how I can write this letter; however, I must emphasize the exigence of what I am asking and it must be supported by undeniable fact.
