Notice they're always "sorry it offended" rather than actually sorry for the awful thing they said. Mainly because they're not sorry for the awful thing they said.

Op is right. Traditionally, the odds ladder went 10/1, 11/1, 12/1, 14/1, 16/1, 20/1, 22/1, 25/1 etc. It doesn't work like that now, but it used to.

As someone who's worked in betting since the early nineties, 18/1 rubs me up the wrong way too.
