I think at this point MS Word automatically recommends a hyphen after any number + quantifier combo. One time it wanted me to correct “three armed guards” to “three-armed guards” which would have changed the meaning considerably.
The number of times MS autocorrect suggests incorrect changes to grammar is laughably high, and most people just blindly follow the suggestions.
And crop dusting, ffs. Spraying actual chemicals on our food is totally fine for these people.
