At the end of service, they ask specifically if you enjoyed the quality of the food, as well as the service, then if and only if you confirm both enthusiastically, do they hand you a QR code that takes you straight to the URL to leave a review.
This seems quite dishonest, as it's pre-selecting only positive reviews. My group of travelers have noticed anecdotally that really lackluster restaurants that use this tactic have 5 stars and a huge number of reviews, and it's completely destroyed our trust in the review system.
Has anyone else experienced this elsewhere?
