I think the bolded is true of the GM at this hotel. Yes, some of the examples given by the OP are amusing, and rightly call out some stupid reviewers. But if you go to the TA page and read more of his responses, you'll see that he often has condescending or passive-aggressive tone with reviews that are 3 stars or less. He nitpicks and rebuts every negative detail. He's playing a game of online review one-upmanship which is unseemly for a GM at a nice hotel.

Sometimes he doesn't get his back up; here's what he said in response to negative comments which were left as part of a 4-star review: "Rest assured your feedback on linen and amenities has been duly noted and I have addressed your concerns with my management team to ensure we focus on lifting our service levels and attention to detail in the areas you have highlighted." He would better serve his hotel if he took this attitude more often. Not every bad review is left by a chronic complainer; sometimes hotels actually have service failures!
