The Definition of Lying

If you are new to the trade and in fact if you are not this will be astounding when it happens to you for the first time, by this I mean those who lie to your face that they have had a lovely time, food was beautiful etc and then what happens is a review pops up that from the descripition you know exactly who it was and they state they had a horrible time. When did this become acceptable? It is not the review I object to but the lie on the point of departure if they had simply stated they were checking out and left I would mind less but the ones that state how much they enjoyed their stay and then stab you in the back baffle me. I think as well that if members of the public had any realisation of how reviews personally hurt business owners as well as professionally hurt them they might think twice. I have neighbours in the industry moved to tears over hurtfull and untruthfull reviews and some have even taken people to court. I believe in customers reviews but not without any accountability. For example the good hotel guide if there is a bad review they send someone undercover to check. This sort of system or something similar would be something I would strongly support as I am sure would most of the industry. I have also had neighbours and friends held hostage to the threat of bad reviews ie do me a discount or else Surely this is something we should all stand against.
