Misspellings are misspellings. They happen, nothing to get worked up about as long as you can decode what was said. But whatever, if it annoys you, it annoys you.
It's been a couple of days now, and I'm replying through the response reply so I'm lacking rereading the context. But my memory here, was someone was explaining it as a potential joke in a typical social fashion, where you'd expect people to have a bit of chuckle but know that's not really the case.
Instead a bunch of people are getting so literal and piling on them for not being correct, I suspect they already knew they were unlikely to be correct.
It's the kind of response that sucks the fun out the internet. It just teaches people, no-one will appreciate a bit of playing around and everything becomes a little more sterile.
