Will professors ever refuse to write a letter for a student with an A?

I’ve been taking a number of prerequisite classes in preparation for applying to an MS program that’s a completely different field than my BA. One of my courses is a lecture class with dozens of students, and even though I’ve visited his office hours several times I doubt that he remembers my name. However, I have an A in the class (actually the second-highest grade).

But I’m feeling nervous about asking him, because I don’t get the feeling that he particularly likes me. Will professors ever refuse to write letters of recommendation for a student with an A? Should I ask him in-person or over email? Should I ask him before the course ends or after (my earliest deadline is September 15 and the course ends August 12, so I need to ask him soon)?
