First-time poster here... Saw the same thing at a store last week. Thought I'd found a goldmine but turned out to be a fool's gold. Nothing's really free, huh? Good looking out, OP.
Okay, but really, who doesn’t proofread their texts, especially ones to the boss? Autocomplete and autocorrect can be messed up, sure, but you gotta watch out for those kinds of things. Hope this little mishap serves as a lesson!
