Yes, during my corporate career I can't remember how many times an engineer left the "l" out of public.
A friend of mine left the L out of public out in a newspaper article decades ago and is still embarrassed about it.
I'm not sure if this is apocryphal, but years ago I read about a headline on a story about a governor signing a bunch of new bills into law that said "Governor's pen is busy" and left out the space between pen and is.
I think my iPhone autocorrect tends to err on the side of wholesomeness. So if I write "shut" it doesn't automatically change it to "shit," even if I actually meant to write "shit."
