JenniferEight says, "However to try and make the shop think it came from there when you know full well it didn't is wrong. As is lying by omission."
That might be a reference to me saying, "Neither they nor I mentioned where it might have been bought." TBH, I'm not sure why I wrote that on this thread.
In actual fact, with my incident (partly because of this thread) I showed the Waterstones' person both identical pristine books and told them the facts: that one of them had been bought from Amazon, and one from Waterstones', but I didn't know which one.
I have been wondering why I wrote "Neither they nor I mentioned where it might have been bought." I THINK it was because I was trying to simplify what I thought the discussion was about: the economic issue, because under the economic argument doesn't matter where it came from.
Whereas, of course, this discussion is about two different issues: the economic issue AND the intention issue.
The intention argument is all about morality, which IS about where the book came from, and lying with intention, and lying by omission.
In attempting to clarify one issue I blurred the lines of the other. Ultimately it doesn't matter though, because my anecdote is just one of thousands, and it's still allowed both tracks to be aired.
