I thought it was kind of weird, even for X-Files.
While I am not in fear of obsessive machines getting - basically, revenge over a lack of a tip - I've always seen automated options that don't allow for
"nothing" - "none of the above" -- or options where opting out just doesn't seem to work.
I *know* I've called places where the voice mail asks me if I want to comment on their service after the call -
and if I click "No" - it hangs up.
