Customer service can be a tricky skill to master, I still fail at it all the time because I can be tired, annoyed, or frustrated with something irrelevant, so I sometimes unintentionally come across as an asshole if I provide a quick and blunt response for example.
I also would have given the answer that it's ready when it's ready, or more likely, not answer at all because I will make that clear in a post any time I do actually know.
It is very helpful to have someone knowledgeable answering questions for me, but people have certain expectations when engaging with a legitimate business. Pleasantries will go a long way, even if it's a performance, and everyone knows it. While we don't know each other, you are acting in my place by answering meta questions, so people have expectations tied to that.
