All of the reviews before this one, the profiles were all made on the same day and have only ever given one review, which happen to be given to this place. And they all happen to be very positive. It looks similar to when a business owner has all their friends create an account to leave fake reviews, or pay strangers or bots to do the same. Then, after this low review got written, once again, two more fresh accounts were made on the same day, to add even more fake reviews to increase their average star rating after psilip's review brought the average down. You can also look at the low quality of the profiles that were created and how multiple of the profiles have similar info.
