Bought a voucher for a meal during the shopback and groupon sale. Went and didnt have a good experience at the restaurant.
Got an email from groupon asking to rate and share experience. Gave an honest rating and review. Never saw it published, checked a few hours later and only 4 to 5 star ratings with positive comments were published.
Beware the fake "reviews" & ratings for services and restaurants on their website.
i did the same, on the ad when you click on the review you will see the 1,2 or 3 stars review but if you click on view all you wouldnt find anything less than 3 stars.
i would say if the restaurant has less than 4 stars it should an alarm bell.
