-literal meaning of Spooky23's statement: it's unreasonable to expect ice in the middle of summer.
-sarcastic meaning of Spooky23's statement: it's completely REASONABLE to expect ice in the middle of summer.
personZ acknowledges the sarcastic meaning (that it is reasonable to expect ice in the middle of summer), and is pointing out that based on the article, the guests actually DID in fact receive ice, making Spooky23's sarcastic statement not very relevant; the issue was that they had complaints about the attitude with which it was provided.
Edit: unless perhaps personZ edited his original post.
