Perhaps I have become a bit of a curmudgeon in my advancing years, but it seems to me that, the older I get, the more annoyed I become by "official" communications with obvious grammatical errors. Far be it from me to criticize, considering the fact that this blog is almost certainly rife with such errors. However, I think a consumer facing business should be held to a higher standard. Take the sign below, for example. It's a classic misunderstanding of ensure vs insure.
What's The Difference Between Ensure And Insure?
Insure is used for referring to financial insurance policies.
Ensure is used when the meaning is "to make certain".
Sure, some style guides claim that ensure and insure are interchangeable, but these are the same folks that claim that "literally" can be used in a non-literal, figurative sense. And don't get me started on that one.
