starting a sentence with "direct all vitriol at" and finishing it with literally anything is so bizarre?? I mean definitely don't go after the author, but also it's not actually normal to react with "vitriol" toward anyone because your order got delayed!

Yeah, this wouldn't have been great even if it had been "complaints" or "disappointment", but "vitriol"? Why would you phrase it LIKE THAT in the first place...
