it really steams me when a customer returns an order for revision because it's APA instead of Chicago, or something-- really, you can't change this yourself?
If a specific citation style was requested, they have a right to a revision. That said, customers have no right to expect any revisions like that otherwise. In fact, I'll admit that in the States, we do not study citation style very much; it's something most of us have to become familiar with "on the job" and it can be a royal pain.
Also, customers should know that from our point of view, if you insist on any citation style that requires page numbers, you've just dramatically reduced the chances that some of us will bother taking your order. Let's say that I've written (literally) 100+ papers on Constitutional Law or Nursing or Criminal Justice or Business Management. After a dozen or so papers on very similar topics, I don't really have to look all that much up because even a dope like me can remember a few dozen books and journals in each of those topics including the names of authors and publication dates. Most of my A-quality essays on those topics are written without even glancing at any sources because I'm sure what I found there many times before is still there. I write the paper and then insert the appropriate in-text references for anything that requires a reference.
If you force me to actually dig up all those books and journals to find specific page numbers (and the first names and middle initials of every author), that paper just became much more of a pain that will waste a lot of time to find specific pages. If you're assigned MLA, you have no choice; if you're not, just let us choose what style to use. I cannot tell you how frustrating it is to see papers I could bang out at A-quality in an hour or two but with such specific demands for references that it's not worth the bother.
Also, if you submit 20 pages of your textbook in 20 individual scans (some of which can't even be viewed clearly or printed out), I click away from your paper as soon as I see a string of .gifs on the resource screen. That's also a shame because sometimes the choices customers make in submitting files is the hardest for them and also the least convenient for us.
Finally, if you clutter my account with a rewrite request asking for something (like a thesis statement) that's right there exactly where it should be because you haven't even bothered to
read the paper you had me write for you, I'm sorry, but I just don't have the patience to respond except to clear it off my screen and refer you directly to customer service.
