I always found it somewhat rude to approach someone famous and take their photograph or autography

I agree. I have met a number of "famous" people and have never once asked for an autograph. I do think it rude, and also I really have no interest in having their signature on a sheet of paper (with the exception of perhaps a blank check. ;~)).

But if I ever had the pleasure of meeting Foote, and if I had one of his books at hand, I probably would have been tempted to ask him to sign.

I do have some signed copies of books, but always obtained them at book signings. The only autograph I have is of Dr. Jonas Salk, and that hangs on the hall of my study.
