Yes, I know that we say "eight dollars" and not "dollars eight" so it may make intiuitive sense to a person who's just learning how to make their way in the world that we would put the dollar sign after the number, but no. No, no. no. That's not how it works. That's never been how it works.
I think the irritating thing about it shows that the person who writes like that doesn't read anything or notice anything.
(I know the graphic at the top of the board was likely not made by anyone here. I'm just ranting!)
