Well, here's another one of those opportunities to reply to two different postings at one time (I always think I risk being called a pedantic nitpicker or vice versa if I post one reply and then another back to back).
Anyway, Helen, "post no bills" refers not to the kind of bills you pay, but to handbills, which are printed posters or notices, which used to be always plastered up on any convenient surface. You don't see them much anymore, since there are now better ways to advertise a prizefight, or a going-out-of business sale, etc.
Dr. Bill, re pill rolling. I was brought into this vale of tears and treated for my first 12 or so years by an old homeopathic MD (and I mean old -- when I was 8 years old, in 1947, his daughter, a medical missionary, retired at the age of 67 or so -- old Doc Hartmann was a graduate of Hahnemann Medical College in Philadelphia, a very well-known homeopathic institution, where my mother went to nursing school, and given his age he must have graduated before 1890 and he was still practicing in his late 80's) and he always rolled his own pills in his office. They were the usual homeopathic "pellets" -- very tiny pills with a base of sugar. You always went home with pills; if you really didn't need any, I believe you got plain sugar pills. [Early use of the placebo effect?] You didn't swallow these pills with water; you put them under your tongue until they melted. I believe this is part of the theory and practice of homeopathic medicine, for which I have considerable respect; after all, it worked for my grandparents, parents and myself.
