How about people who work on something and then present it with ''Wolla''? Didn't they ever learn that it's ''Voila''?
Actually, it's "voilĂ*" (with a grave accent). Sorry, couldn't resist - I generally don't comment on other people's spelling, but since we're on the subject...
We all misspell from time to time. It's no big deal, really, but it is true that some people don't seem to care about spelling at all, and that can be annoying.
My pet peeves? Hanger (hangar) and Satio (Saito).
