I don't think it's a fake review... And your analysis of what you consider grammatical errors is brilliantly funny!

There is nothing wrong with thr parts you highlighted, all are perfectly acceptable uses of English. Highlighting those phrases actually does more to show your own lack of understanding of English grammar than it does show up the op!

The only one that is debatable is the use of "Gives" without the pronoun 'It' although it is clear from context she is referring to the guidebook she was given. And if I had a pound for every time you have failed to capitalise a proper noun, I could probably pay for my flights home at Christmas!!

And the last part you highlighted looks to be an autocorrect error from 'how' to 'out'... Although given the howlers you have made in the past, you really ought not to be judging other people's use of English... Your own defence was 'descriptive' grammar, so again you can't claim this and then correct the use of someone else's English! Either grammar can be descriptive or it must adhere to rules. You have endorsed the former, in which case picking holes in the grammar use of others is just hypocritical!

You think it's fake because she's had a good experience, simple as that!
