Depends on one's definition of "replace."  See below.  The only
exception I can think of is when the last customer hangs up her hat
for eternity, which is not relevant to any profitable business plan
(unless you're in her will).

True.  Brock's "definition" doesn't deal with that, either, which is
why I elided that point in the first place.

Please note the 14th word in your second paragraph.  The defense rests.
